I'll chip in for 'closed'. 13th Age handle feats really well, and basically uses them as 'add-ons' to class abilities, allowing you to emphasise specific abilities of your character and so differentiate them from other members of the same class.
I found 3rd edition feats to mostly be dull, and in my experience there was only actually a very small subset of them which got used, which tells me that having a big list to pick from is meaningless unless they are genuinely all worthwhile.
I would also add that I find feats which add numerical bonuses very uninspiring (especially combat feats which provide adds). They have zero flavour and rapidly become 'must have' for all the wrong reasons.
