Definitely much better available, but at the right price (very cheap to free) which is unlikely, then yea i'd have him as a decent backup. But as a target for consistent first team football, we should be aiming higher.
His attitude in his career has been disgusting, but wouldn't use that against him to say he is a jank player, as he isn't. Who knows, his attitude might change at liverpool, as this is a club that has achieved extraordinary things, so to subdue Barton wouldn't surprise me.
Overall though, no.
