As for "what's better", it really depends on where you want your game playable, and if you can tolerate the strange bugs Construct Classic can have.
I'd recommend Construct 2 overall, but you can use Construct Classic to learn they way Construct 2 does things.
Construct tools in general are amazing, and out of everything I've used before they are the best for 2D games.
