But, Xavier was still alive after being chopped into pieces and reformed himself with ease, so he's certainly more durable if not potentially unkillable. Rick would have to probably vaporize him to put him down for good. He's also physically stronger, too, considering he was able to casually splatter two monks while Rick can't replicate that with his own strength.
Rick's weaponry is more straightforward, while Xavier's abilities are a bit more haxy. Xavier can turn a man into a sandwich with one touch, alter the past just by remembering it differently, recreated the universe by playing his shakashuri with a clone of himself, and once tore apart the fabric of space with his bare hands.
Rick's greatest victories usually come from his planning and knowledge of his opponents, but even then he's far from infallible even with planning - just look at the acid vat episode. In a Death Battle type fight with no prep time, where he only has what he usually carries on him, Xavier's unpredictable near-toonforce abilities should net him the win.
