Trifroze
all is cheese, all is jank
I already watched Capcom Cup once on Sunday though ¯\_(ツ)_/¯I'm not saying that the neutral-favoring players DON'T do the combos, or that the combo-favoring players just forget about neutral, but that there's a difference in motivation and mindset as a result.
Like watch this actual SFIV match from the recent Capcom Cup. It's Evil Ryu so it's not quite the same as Ryu, but you can see just how much Daigo is constantly jockeying for position, and the very act of walking forward or backwards at key moments is a big deal. Before a hit is even landed, the game is considered intense. That seems to be the environment where SFers thrive.

Though keep in mind that there are certain characters even in SFIV that seem better for Smashers (Makoto, C. Viper).
What I'm saying is that if you try to play Ryu in Smash like you play him in Street Fighter, it's no doubt going to be hard because you're literally just limiting yourself with that mindset. Then there's also a different kind of "extreme" group, one that is overwhelmed by Ryu's extra moves, SF inputs and jab/tilt cancels when in reality you'll rarely use let alone need half of his moveset and the inputs and cancels aren't any more complex than many other inputs we constantly do in Smash 4. Ryu's are just less intuitive to those who've never touched SF.
The result is that you hear people calling Ryu demanding so often and from so many different sides that the opinion becomes a standard in the community, but I think it's sensible to argue that for someone who has never touched any fighting game including Smash, many characters could easily prove to be a lot harder to learn and master than Ryu would.
This is not to say Ryu is easy, but I think people who are constantly bringing up his complexity are misusing and/or misunderstanding the character, or just trying to boost their own status as a player.
