He never said that. He just believes that it’s newer than ST and it’s still being played so that’s the one they chose. It’s complete horseshit. Most hardcore players use ST as the tournament standard, and if they use HSF2, it’s to play ST. HSF2 is just a very prevalent arcade board. Clearly, he’s out of touch with the real scene itself.
I think the real reason is that you gain access to all different SF2 characters, which would be seen as “fun” to the more casual players. You get the best of both worlds this way.
CE/HF Ryu is way better than ST ryu. The speed and recovery of his fireball basically makes him a shorter Sagat. This, combined with high damage and priority on his grounded kicks and jump attacks, makes him a monster.
Super Ken is the best. While previous versions are also solid, Super Ken has both the juice kicks, which is pretty essential to certain matchups, alongside having a really good fireball, uppercut, pokes, etc… He’s much more well-rounded.
Honda seems tied between ST Honda and Super Honda. S.Honda is actually better than ST Honda in certain matchups, so it kinda equals out.
The real HF Blanka is insanely better than ST Blanka. The problem is that HF Blanka in HSF2 isn’t quite the same. A lot of his hurt and hit boxes are all screwed up to hell.
As far as Vega goes, his damage/stun potential is higher than ST Vega if you prefer the ground game. But otherwise, ST version is vastly superior.
Old O.Sagat is still available in the game, but you need to input a special code. But even then, CE Sagat’s damage+stun potential alongside his tiger knee which basically acts as a dash, is much better.
