Is lemmy.world more active than lemmy.ml? - Lemmy.world

So apologies if this is a stupid question as I’m new to Lemmy. Came from Reddit. I moved to lemmy.world and have noticed that lemmy.ml [http://lemmy.ml] has been popping up as another featured instance. What differs from lemmy.world vs lemmy.ml [http://lemmy.ml]? Is .ml more active? Part of why I ask this is because I downloaded the lemmur client on my phone and it defaults to lemmy.ml [http://lemmy.ml]. (Yes I’m aware that app is no longer being maintained) Again apologies for the stupid question.
