Better.........
That might mean features available on the board. Such as type and number of drive ports, number of RAM slots, number and type of monitor connections; number and type of USB ports; provider and version of LAN and onboard audio.
If that's what better means, walk down the spec sheets of any candidate at the manufacturer's web site.
Or it might mean reliability, in which case spec sheets mean little, so take a wild guess.
Your work load intensity might come into play regarding heat and therefore affect cooling requirements.
I guess you've listed 1 ATX board and 2 micro ATX. If all 3 fit your requirements, there may be no need to consider the ATX model unless its underlying components are superior in some identifiable way.
I would give some consideration to the vendor, return privileges, customer service type issues. Issues on new motherboards aren't rare.
Any recommendations you get may be based on spec sheets or on someone's personal experience/anecdotes.
Try to understand the basis of any recommendations and judge them accordingly. Try to accept that randomness and quality control issues beyond your control may have more effect than you'd like.
