3/5/6 hour layover

Hello everyone I’m from NYC and I’m planning a trip but I’ll have a layover at LAX either 3 or 5 or 6 hour layover. I’m flying Delta and I do have TSA PreCheck. I’m mainly looking to try In & Out and possibly look around a bit. I did notice that there’s one on Sepulveda Blvd and was wondering if I should pick the flight with the 5 or 6 hour layover or if the 3 hour layover is doable, thanks!
