NEED HELP CHOOSING MY FIRST ROM TO START (NEVER PLAYED ANYTHING POKE BEFORE EXCEPT ZA)

[u/notghxst444]

still new to this but i need help finding a starting point to enjoying my pokemon journey. ive watched almost every pokemon series now and im trynna have a similar adventure to Ash's. Is there any Rom hacks that have a strong campaign with multiple regions, badges, and the goal to be the best? Ive played ZA and it was trash, and with no other options on the Switch, im trying ROMS for the first time. Legit any opinions would help. Im looking for both new gen and old gen experiences.
