Method Inert Gas: Settling for Ar because N2 is too hard to get

[Not A Fan]

Well... it seems like the universe does not want me to get nitrogen.

Is there any reason why one should prefer nitrogen over argon? Does argon cause more discomfort or something? Because it seems a lot easier to get argon and there are more sizes available. I think that's why I'm going to buy.

Does this seem like a good idea?

Edit:

Lots of problems reported using argon because it weighs more than nitrogen. But if it does work, it should provide approximately the same hypoxic death as nitrogen. People have reported nausea from briefly testing argon gas setups, not the case with nitrogen. It seems do-able but I'm already preparing myself mentally for something else to go wrong.
