Honestly not that big of a deal. When something is hyped up users who either didn’t or barely used Twitter (X) probably joined in. It boosted their initial numbers but again they fell off. They’ll grow as unique content grows. That happens with everything, as will the case be with Lemmy. Growth isn’t linear.

I switched from Nova a while ago. I’m trying out Smart Launcher right now and generally am pleased, but I ran Lawnchair for a few years and loved it.
