It's obvious that equipment doesn't have control. It's just that doing certain things is easier with certain equipment than others, depending on what you're trying to achieve.
But in the end, the difference isn't that big as long as we're talking about relatively "standard" equipment. Though it does make a difference when we've pushed all the other buttons to their max. It's not strange that people want to optimize their equipment to their game/needs so that they have maximum control over it.
When I see these "control" ratings on equipment, I know that it's rubbish. But it also does tell beginners something. Basically: low control rating = ball flies out fast. High control rating = ball doesn't fly out fast.
When I've let people who don't play TT play with my racket they'll say something like "the ball just flies out" and when they play with those crappy premade rackets they can touch the ball without much rebound.
If the only goal was to endlessly put the ball on the table without any necessity of making the game more difficult for the opponent then you wouldn't need faster and spinnier equipment. But that isn't what it's about.
If you have solid technique, a strong body and have practiced a lot then it's no good using very slow and non spinny rubbers, you won't be able to utilise everything you've learnt to its potential so you must find some balance of relatively fast and spinny equipment.
