Lemmy.world is too big
Lemm.ee is federated with hexbear and lemmygrad, something that is not very welcoming to new users (see this thread: https://sh.itjust.works/post/28798607/15305964 )
sh.itjust.works names contains "shit", which can deter users
lemmy.ca is Canadian-centric
feddit.org, as you mentioned, is German-centric, but technically English speaking too
dbzer0 federated hexbear
programming.dev is topic-centric (and has a database corruption for the last month https://programming.dev/post/20515601?scrollToComments=true)
blahaj is queer-focused
discuss.tchncs.de has a difficult name
lemmy.sdf.org does not defederate anyone
lemmy.zip is federated with hexbear and lemmygrad
sopuli.xyz doesn't have "lemmy" or "feddit" in its name
beehaw is way outdated
infosec.pub is topic-centric
aussie.zone is country-centric
midwest.social is region-centric

The next page has reddthat.com which is known to have federation issues with LW due to its location in Australia, and lemmy.today which does not defederate anyone

Honestly I'd say lemmy.world is probably the ideal for redditors, I agree it's too big, but it's probably the safest option for people without a lot of knowledge. sh.itjustworks is also IMO fine if you know the person isn't offended by language.

I agree it’s too big

That's the main issue. Its size creates 5-days delay with some instances

The issues have been here for months, are not going to be fixed any time soon as the latest Lemmy version still has issues like the pictures one: https://github.com/LemmyNet/lemmy/issues/5196
