If those are your only choices, the UA lounge is better. Maybe someone else has an update, but for the longest time the new AC lounge didn't have a liquor licence, so that's a pain. But tbh, neither is spectacular, nor dreadful, as both have been renovated recently. The deciding factor really is where your gate is. Neither one is worth chasing, and even having TSA pre at EWR can sometimes mean jack squat. Doesn't work if the lane isn't open, which I've found multiple times.

I'd also say don't bother with the "Art & Lounge" pay lounge, it's only really useful if you have a long time to kill and no status of any kind.
