I always thought it was mostly a laptop issue, since laptops easily have less amount of disk space than a desktop does, so naturally it's all based on personal preferences, based on the person's real world interests, and game play preferences. For example: A person who's a builder would most likely prefer OLS, while someone who still likes their classic Sim items, will want HELS. A person most interested in silly random objects will lean toward KPST, but maybe a more realistic person will want Town Life.
