GGST purchase advice?

So I am looking to get into real fighting games for the first time (I played games like smash but that's not the same) and wanted to get into GGST, but the amount of DLC is a bit daunting. I really don't know which characters would be what I'm looking for and so I thought that it would be better to just buy the Blazing edition and figure it out from there. But I also worry that it would be a waste of money as buying all the characters at once and then only finding 1 to be worth it could be wasteful. I did some research and learned that I can't just buy the base game and then get the Blazing edition added on later, so I'm in a pickle.

Should I just get the base game and then pick up the DLC characters that look cool later, or should I just suck it up and buy the Blazing edition now? Is there any reason other than characters to get the Blazing edition?
