Completely a matter of taste Are you going to break down in tears when faced with 3 Bb5+ on a semi regular basis?

2..e6 very suitable If you're happier with classically going a quick d5 but can play in others ways anyhow.

2.. Nc6 is another entirely possible move order for the Kan of course. 

Also worth considering switching your move order around between these move 2 things, so you don't present a fixed target for anti players.
