They both were fairly formidable opponents for Trunks and Vegeta, but they were eventually defeated through a legitimate amount of effort. Even in the end both Vegeta and Trunks still had energy left to spare to transform a couple more times. They seem to be around the same level of power...so if both of them fought Meta-Cooler together, I think it's safe to say Meta-Cooler may very well loose.
