I started on Lemmy World, because I could. I didn’t truly get the decentralized nature of the Fediverse, so I went with a larger instance thinking that was best for longevity.
Now that I understand how things work, I’ve picked up a few more accounts/instances (including one on Kbin) as backups and currently use Lemm.ee as my main account.
Ultimately, I would like to start my own instance for me and my family.
Adobe Suite. As much as I loathe Adobe, as a graphic designer there is no way to bypass them.
Affinity is making some headway on individual apps and there are a few others, but as a whole suite it just can’t be beat.
