I’ve been to both and can’t say one is better than the other… it’s no LH FCT/FCL. You’ll have better food and drink on the plane anyway. But I can say it’s definitely not worth the walk twice unless you had like a half-day. You can even stop by the Air Canada lounge en route!
(And i think you’re coming from SFO, so the Air Canada lounge there is new, nice and better than the United Club so if you’re looking for a lounge before your flight there I’d check it out… just plan for a 10-15 min walk back to the UA gates)
