Okay, so after voting, I was actually surprised to see Lucky Palms and Sunlit Tides further on the list. I like all of the towns in their own way, but I tend to vote them in order from my favorite to least used as listed here:
1.Lucky Palms I love Lucky Palms because of its user-friendly atmosphere and limitless possibilities. It's great for builders, like me, who wants to test out different house plans. It's great for playing multi-generational games due to its easy access, low load time, and low glitch/tech issues. It also has some great characters that are easy to befriend and fun to play. Also, the starter homes are decent; in fact, I would argue that they're the best I've ever found.
2. Sunlit Tides Having grown up in a desolate area of northern Nevada, staring at snow-covered mountains all the time, I long for warm sandy beaches and beautiful crystal water in the real world. Sunlit Tides is my fantasy world, especially since there are so many lots that are right on the beach and backed up to the water. I love this world. It's only downside is its navigation. I sometimes get disoriented while in map view because everything is on a peninsula and then there's the volcano rock in the center. But the views in it are breath-taking, even on a computer screen. And the tropical aspects of it are inspiring for me.
3. Appaloosa Plains Having grown up in desolate northern Nevada surrounded by ranches and snow covered mountains, Appaloosa Plains hits close to home in reminding me of my childhood landscapes. The ranch-style homes are similar to ones I grew up in and that I visited as a kid, so I feel right at home navigating all the houses and the landscapes. However, it's still a little too restricting for me at times, and I'm not a fan of all townies owning pets. Though I am a natural pet lover, especially the 3 playable types, I do tire from the repetitive actions of the pets.
4. Riverview For a lot of games in which I want to test out new content, new skills, or to further explore established content and skills, I always come back to Riverview because of its familiarity, its user-friendly set up, and its townies. I do find the town center restricting and small, and the houses a little too far from the town, but I still like it for its user-friendly set up and beauty.
5. Aurora Skies Though I have this one listed pretty far down on the list, it may move up eventually. I have it listed down a little because of its newness and unfamiliar territory. I think that once I sit down and really play it AS will move up in my list of favorites. For now, it's here.
6. Monte Vista I actually like this one, except for how some of the lots are positioned. Save for the large lot by the fish pond, the lots are restricting on building (and I'm a builder...50+ lots only, please). So, this town isn't really used by me. Also, it's difficult to want to do much when the stores are in weird areas that take a lot of travel time to get to. But, it does have nice views.
7. Sunset Valley I wish this one was higher on the list, and it used to be my number 2 town to use. But, with all of the EPs automagically placing lots on the very few open lots in this town, it's no wonder it's not a fave anymore. Again, I like to build. In order to build in SV, I have to go through and delete lots. And having all of the EPs causes major lags, so removing just one 40x40 lot takes forever. Therefore, I'm not a huge fan on SV anymore. However, it isn't at the bottom of the list simply because I did use it for ID research and ideas. It is useful for that.
8. Moonlight Falls When Supernatural came out I was so excited and I couldn't wait to play in the new town provided! But, once I got into to the town (it takes forever to load) and started to look around...I wasn't so impressed. Sure, it's got a lot of features and a lot of room. But, surprisingly, it lacks in open lots. It really irked me because there were areas that looked perfect to place a home on, but I didn't want to go through the hassle of waiting to load world editor just to build in the town. It may eventually grown on me, but I actually don't play the supernaturals (which is odd because I'm such a fan of fantasy literature and the paranormal). So, Moonlight Falls lost its appeal after I studied it closer.
9. Hidden Springs This is only on the list because of how pretty it is. It has some gorgeous views. But other than that, nothing is special about Hidden Springs. It's glitchy, it takes forever to load, and I can paint my grass in any world as green as HS grass. I never play it anymore.
The rest of the worlds Twinbrook, Bridgeport, Barnacle Bay, Starlight Shores, and Lunar Lakes I rarely play in. Actually, I got the Showtime EP for its content (pool table? Must have pool table for my super awesome lounge/dignified man cave). I think I looked at SS once and after my game started freezing while just looking at the town center to get a better idea of its layout I exited and never went back. Twinbrook is just...ew...too swampy and lots are way too small for me. Bridgeport was fun for the apartment-style living and learning about celeb status. But forget traveling anywhere in Bridgeport! Also, I'm not a night owl myself, and clubs were never very appealing. Barnacle Bay was alluring, and I bought it to try out for the ID challenge. But no special seeds? Forget it. I actually have been thinking about reinstalling Lunar Lakes, but then I remember the horrid landscaping and the trees that just won't disappear (those fantasy spike trees always block my view). Also, the houses are not user-friendly, and the sci-fi aspect might be fun for some but I'm not too keen on it.
I would love to include UC in the top of my list (or even say I've played it), but alas...I only peeked into it once and it was right after it first was available on this site. It was so cool too! But, the world refused to load properly, and the layers of content really slowed my game down to the point where my sims froze every few seconds. Of course, that could be because I have so much stuff downloaded from the store and from Origin.
