I've lived in both, too, and I like the condo/apartment life better. The better, easier access to libraries, restaurants, shops, parks, cultural venues within walking distance or a short transit ride never gets old.

What wears thin for me is living in the suburbs with no transit access, one crappy little convenience store a thirty minute walk away, the neighbourhood "park" is just a swing and slide set on a patch of grass rather than something with nice gardens and walking trails, and, if you're lucky, a McDonalds or KFC/TacoBell on the arterial road through the neighbourhood, and nothing to do but sit on my thumb when not at work.

I'm an introvert but that gets boring even for me, but you sound downright isolationist. You can choose whatever suits you best, but stop making he mistake that everybody wants or likes the same thing as you. Meanwhile, I'll continue to chose the neighbourhood where I can walk to more restaurants than I could visit in a month even if I ate out every night.
