Finished JFA. BRAVO! (Also a question about save files)

I'll keep it brief, but JFA has honestly given me the best cases, and Farewell, My Turnabout is my favorite one now, second place going to Turnabout Goodbyes. This last case was amazing, long as hell, but that's good, because I love this series! And the conclusion had me smiling like a fool!

Anyways, my question about the save files is if I should overwrite my JFA one as I go into Trials and Tribulations? I played PWAA when it was on Gamepass, but didn't get to start JFA before it left, so I bought the game on the Switch (So as to keep all the Ace Attorney games in one accessible device for roadtrips) and started from JFA. Now that it's over, should I overwrite the JFA save or just make a new one?
