I've got an M2 iPad Pro, running 16.3.1 and jailbroken with UTM HV. It's very fast, about 96% of the native speed, however you can only use up to 5 and a bit gigabytes of ram before getting terminated. The linux experience isn't too great either. It tends to be quite buggy and crashes a lot, I've tested Ubuntu 24.04 and Fedora 40. Overall, it's cool but too buggy for me to use daily.
