I find the actual user ENGAGEMENT significantly worse.
That's the point though?
I don't use Mastodon for engagement but a feed of interesting stuff across a variety of subjects posted by others. Masto is a little bit like an RSS feed, I don't castigate RSS for that either.
Therefore I've come to the clear scientific and educated decision that Lemmy is simply superior
Sarcasm aside, that's like saying a screwdriver is better then a hammer.
