Hey! A few questions from a Cobblemon beginner.

My friend and I just started playing this beautiful mod, and I had a few technical questions, because I'm torn between 2 options:

Should I play the "Cobblemon Official" 1.21.1 Modpack, which has an updated Cobblemon 1.6, or create different, custom modpack using Cobblemon 1.5.2 in 1.20.1 with custom mods such as Cobblemon Rider, Legends Untold, Megamons, etc..?

What do you think is the best option? I don't want to miss out on any cool feature!
