re: P trap help - how would you repair?

Yeah threads are the same. Took the old p trap to the plumbing supply store and they confirmed. I was very careful threading the new piece on to no cross thread it. If I felt resistance, I’d back it off and wiggle it a bit while turning. It went fine until the final two threads and then felt like the threads were messed up. Not smooth at all. I feel like just gluing it up. Yeah I’ll have to cut it out if I ever need to replace/repair anything but I’d have to do that now if I went with option 3.
