The advantage of TMs 51 - 55 is that, after they are used, they disappear and can be erased from the Pokémon's moves.
However, TMs cost money, whereas HMs are free.
These might not work on all versions. I know they work on Red, but I don't know if they will work on Blue.

These codes allow you catch any Pokémon in certain areas
YOU MUST FIGHT IN THE GRASSY AREA WEST OF CERULEAN CITY FOR THIS CODE. THIS IS THE ONLY AREA THESE CODES WILL WORK FOR.
Red only codes : XX1-91A-7FC + XX1-93A-F7E + XX1-9BA-5DB
Blue only codes : XX1-91A-7FC + XX1-93A-F7E + XX1-9BA-6EB
This set of codes lets you fight any pokemon you want in the grassy areas just north of Pallet Town. They work on the Red or Blue USA versions. You will not always get the pokemon you want the first time you fight. You may have to fight a while before the one you picked comes up.
XX0-E1A-F7A + XX0-E3A-F7C + XX0-E5A-F7C
Use this list to pick the Pokémon that you start with or fight. Even Mew and Missing No (the two hidden Pokémon) are here!
I added Missing No myself.
