There is no real difference.
PADI recommends that OW divers stay above 60 feet and requires instructors to keep students at that limit.
PADI recommends that AOW divers stay above 100 feet and requires instructors to keep students at that limit.
PADI recommends that Deep Diver trained divers stay above 130 feet and requires instructors to keep students at that limit.
Neither PADI nor any other agency in the world has the legal power to limit the dives you do on your own.
UTD and PSAI may make the recommendations you describe, but they have no more power than PADI does to stop you from doing whatever you please on your dives. Local authorities have that power. Dive operators have that power over the people who use their services. Dive agencies do not.
It's amazing how many times you have had to post this. You should preface the statements with "this is a recording."
