What is your favourite lightweight microcomputer for PiHole+Unbound?

I’m trying to free up my Pi 3b which is overkill for a PiHole with Unbound DNS and am looking to try something other than a pi zero. What are your recommendations! A few brands that come to mind are LibreComputer, NanoPi, BananaPi, and OrangePi. Bonus points if it’s possible to set up with POE!...
