Apex is price comparable to 105, both are the lowest end 10 speed groupsets offered by SRAM/Shimano. 2200 is 8 speed, Sora and Tiagra are 9 speed. SRAM doesn't have anything to compare to them. 2200 and Sora have annoying thumb levers, and you don't have to be a racer to dislike them.

Personally, I'd want Tiagra at a minimum, but if price is a problem the cheaper groupsets seem to function fine.

It's pretty hard to find a road groupset that is complete junk. They all work. Some work better, or are more comfortable to use, but any of them are better than the walmart bike grip shifters.
