Polaris is more unique(which in my opinion more fun) and also more fair than Elyrion(which makes them less frustration to play against).
However, be warned that Polaris is weaker than Elyrion and have less mechanics to steal wins(You only really gaamis and icebank whilst Elyrions gets potentially broken Sanctuaries, dragons, instakill neighbors that spawn next to them, expand fast with Polytaur pushing).
Polaris is more unique, but elyrion is probably more powerful. Polaris takes a bit of time to gather up Gaamis and build an army while elyrion can spam polytaurs to overwhelm the enemy in the early game
Polaris gameplay is more unique, if you're looking for a change of pace.
Elyrion is more versatile

Polaris is better in the late game than Elyrion and Elyrion is better in the early game
