Which do you guys think is better?
Well basically, at most elos your opponents are making tons of gameplay mistakes that can be 'capitalized' on.
So quite often it's best to pick the support that you personally are best able to exploit those mistakes with.
Teamcomp is much less of a factor outside of competitive play, largely because of the above circumstance.
Just about any support can be highly effective both in lane and in teamfights-- you really need to be personally good at both aspects of play to best turn that into game winning.
