Alt OSes for EOL Chromebooks

I'm curious if anyone has tried alternative OSes on an EOL Chromebook?

Ive read using brunch can keep them receiving updates (without losing Android/Linux containers)

I tried out bliss is from a live usb last night and it was okay. Honestly the 3 launcher options just send to compete with each other.

Anyone tried any others out? If so, which ones, what was your experience like?
