really snappy but the external speakers are not fully supported yet. I have the model with no HDMI port and just tested an external screen with a dongle... didnt work. The install is easily reversible and keeps macos installed so it's worth a try if you want to experiment.
I installed it to try it out and it seems very performant. I just noticed some bugs (also I had to use the edge kernel for changing screen brightness) and not being able to use an external monitor is a deal breaker sadly.
