I switched from the console to the pc when my daughter moved away and took her ps3 with her. I like the pc a lot better. The controls are easy to use right from the start. I think hair and clothing options are fairly similar in the base game. I really like the base game town, Sunset Valley, and the second town you can download for free, Riverview. There are no loading screens when traveling from place to place in town. To me, that is a huge plus. There's no karma which I personally don't miss and there are badges to earn instead of trophies. There are a lot of lifetime reward possibilities. Another big thing to me is no fire meter, so go ahead build away and have that big garden you always wanted. Also, of course, as you mentioned, edit town and the ability to control different families. When I played on the console, after a few generations saving got to be almost impossible. On the pc, if you use the save as option and rotate through several save files, you shouldn't have saving problems. Oh, and you can have 8 sims in your household instead of six.
I know you're only asking about the base game, and I personally only have a few expansions, it's good to have that option as a possibility for the future. Enjoy!
