I like a variety of sizes for different reasons/gameplay. The problem is the number of lots in each world is limited so can't have a good variety to allow residential and commercial lots to make up a town. It is one of the disappointments for me with Sims 4 although I still love and play the game. After playing Sims 2 and 3 with the ability to place your own lots and make the community a true town, Sims 4 was a real adjustment. I too end up deleting townies to make room for my own sims, but I would have preferred to be able to have both. I use Newcrest for most of my community buildings as a type of "downtown" for my sims to enjoy. But I still really miss the ability to have more community lots in a town and enough residential areas.
