My main reason for not chaingrabbing isn't because I really find it all that cheap. I just think it's really ****ing boring, and is counterproductive in the long run if you don't spend the time learning other aspects of the matchup. Marth can do so many things, and the first thing I see almost every Marth main do vs spacies is "OOOOO GRAB!!!! GRAB GRAB GRAB! UPTHROWGRABGRABGRABGRABGRAB!!!". And then, when they run into a Fox or Falco that knows how to avoid getting grabbed, they complain about how cheap spacies are because they never learned how to actually fight vs them.
I feel like the only times I ever really CG'd spacies earlier in my smash career, I ended up beating players who were considered better than I was. This was mostly because I have always been pretty against CGing, and in those specific situations, M2K asked me to win, so combining my knowledge of actually knowing how to fight in those matchups with a very limited knowledge of how to chaingrab, it temporarily put my ability at a level higher than theirs, and I won. CG is easymode and doesn't really take all that much practice to learn imo, but I don't really find it all that cheap given the nature of the matchups and the advantages held by the spacies.
Edit: If you watch the third match of me vs Forward at Evo, it's pretty obvious that I have no idea how to chaingrab. Everything I did there, I just copied from taking note of what M2K did the day before and that morning, and I pretty much immediately forgot how to cg after that tournament. I didn't practice the chaingrabs before playing that day.
