Acrobat or bard dilemma

So I just bought the game(a little late I know :P) and I have a question :
I want to choose Bard because I am thinking I will get level up faster and I will have a lot of spells by the end of the game with multiple characters but at the same time by choosing Acrobat I get access to those cliff chests ... I am wondering if you get other characters later in game who can jump on cliffs or if all those chests contain only items ... do you getarmor/weapons later on in the game from those chests or all of them contain just items (healing/magic/revive etc) ?
