Ignoring any concerns founded on principle - every Pokémon obtained by that glitch has equal potential to be gamebreaking. A level 100 Beedrill at Misty is a gamebreaker. There's not meaningful tiering to do there.
Of course at level 100 is game-breaking, but I haven't said that, just don't Growl it.
I mentioned Mew because it's impossible to get it without the glitch
and because I used Mew with the glitch several times.
