The Post-Crisis or Pre-Crisis Earths yes Mutants/X-Men would most definitely have it better Meta-Humans were generally excepted and during the Post-Crisis era the DC Earth had decades since WWII of society use to Metas. Post New 52 I'm not so sure the New 52 seemed a more darker untrusting world than the DC Earths before it. Rebirth could be a different story but the history of Rebirth DC Earth is still in flux and hard to judge.
