Tails with "dotted" LEDs aged horribly IMHO so that rules out 1 and 2.
I don't see reflectors on #3 and your car doesn't have them in the rear bumper either so it may be an issue. Also, those tails that make zero effort to conceal the black center where the bulb sticks out look really bad.
Your stock tails look great. You can simply replace the right side trunk section which looks like it suffered water damage, add good quality LED bulbs and code the errors out.
