Using 57 for few days, speed improvements are impressive.
But two things which is going to stop me from complete switch. 1. There is no native websocket inspector. websocket-monitor[0] add-on which supported websocket inspection is not compatible with quantum. Really wish they speed up native support development[1] 2. Double tap zoom really makes it easy to find UI issues. Really wish it get implemented in firefox too.
