I used to do back ribs only. After trying spares many years ago I haven't gone back!
BB's are so much easier to prep. You literally remove them from the packaging, remove the membrane and rub - a couple of minutes. Spares take far more time to prep, but it is definitely worth the effort. The flavor and texture of the meat are, in my opinion, far superior to a BB. I did a cook last summer and was asked to cook some BB's. They were just OK, but didn't hold a candle to the spares I cooked along with them.
This whole BBQ thing is really about personal choices and preferences. Some use foil, purists say it is cheating. Some trim, some don't. Unless you're competing or selling your product, the end result has to please you and only you (and your family). I try different things just for the sake of learning. When I find something I like better that what I am producing now I change my methods. It's an ever-evolving hobby that constantly changes as you learn more. The key is to have a good time doing it!
