Method 1: all you're doing is monitoring a local session. It doesn't matter where you are. If the connection drops or is slow, the pc or pi gets on with it regardless. Just transfer your images at the end of the session.
Method 2: you're controlling the session. Fiber at both ends notwithstanding, if the connection drops or is slow, guiding for example will fail.

The only way we've got remote across Internet to work reliably is to vnc into a mini pc running both indi AND a client. kstars is a good choice;) I speak from bitter 'phone-calls-at-4am experience; I'm quite often the guy on the ground at the telescope end!

Cheers and good luck
