Each server has a purpose/focus/theme/blah/etc.

Some are run because people like to host their own servers and be in control themselves.

What server you choose _does_ matter, because some instances are notorious for certain things known by basically everyone else on Fedi.

If you're looking for a specific type of server, it's fine to ask and relocate after. You should be able to migrate your posts to your new instance unless either of the servers lacked that feature.
