I am going to explain it differently even though I agree with how NextLevel explained things about blades that are a little slower. I just think that there is even more to it.
When you have a fast blade, and your technique isn't already REALLY DARN GOOD (like, semi-pro level good) the really fast blade makes it more likely that you will do several things which all cause your technique to improve more slowly.
First I am going to say what the number one important thing to help your technique to improve is: MORE SPIN. More spin requires more precise contact, finer touch, better ball feel in your hand and the ability to brush past the ball instead of letting the ball to sink in all the way to the wood.
A faster blade, a harder blade, generally has less dwell time and the ball flies off the racket faster. Someone who already has developed the fine touch and acceleration of good technique will still be able to feel what they need to. Then there is everyone else.
So here is what a faster, harder blade will do:
It will feel better to blast the ball and make drive or smash contact so your more likely to continue learning to drive into the ball and much less likely to learn how to brush past the ball and how to control the depth of the brush so that you can decide how much the ball sinks into the topsheet and sponge.
The faster blade will also encourage you to cut down your stroke to control the ball going onto the table. This will also encourage you to use less body, hips and weight transfer and a less useful arm motion since you will likely be cutting down your stroke without even realizing it.
So the faster blade, until your technique is already decently high level, will encourage you to develop a weaker and less mechanically effective stroke.
Whereas, the slower blade will encourage you to develop the skill of holding the ball on the topsheet and sponge for longer. It will encourage you to learn how to accelerate your racket much more. To brush past the ball instead of hitting into it to get more from the topsheet and sponge to help the pace. It will help you develop the touch and feel of finer contact. When your contact is not so good, it won't feel good. And your racket won't help you as much. When your racket is good, you will be rewarded and your nervous system will feel the difference between good and bad contact. With a harder, faster blade, often bad contact still feels good because you get that snap from digging into the wood that you really want only when YOU choose it.
So the faster, harder blades are seductive because it is really fun to use them. However, they do ultimately slow and prevent your development of higher level technique.
When you can do all the stuff from this video reasonably well, then go for faster, harder blades:

, I would like to ask a question. I have Tsp Thriller OFF- blade and I have no problem with the blade, but looking for information for it I can't find accurate info on the plies of it. Tabletennisdb.com says that it's 5 ply with kiri core, but looking at the blade it seems it's one ply.
