Loop vs Tandem's Control IQ

I’m curious if anyone on this forum has direct experience using both Loop and Tandem’s latest Control IQ system? If you’ve used both I’d love to know how you feel about Control IQ. Personally, I’ve upgraded my X2 pump to keep as a viable backup but from what I can tell so far, I’m planning on sticking with Loop. Has anyone here made the switch? if so what do you think?
