I would have preferred the option "Charry Pick", but if its all or nothing, I have to say "nay".
Back in the days, I was all for it, but I had no clue about "balance" or "power creep", or even "nonsense", so its hard to go back.
Barbarian and Cavalier - ok, but were better off as "Fighter" with RP drawing the distinction.
The new ability roll system is horrid, basically "this class gets an 18 in strength, even if you have to roll 11d6 to get it".
Weapon specialization is a somewhat necessary fighter-enhancement, depending on the overall power-level of your 1E campaign.
The Demi-human deities are nice enough.
Pole-arm fetishism...not sure what to say here, ok if you're into that sort of thing I guess...
Some decent enough spells.
YMMV
