Depend on your skill. I like hard sponge so t05 is my favorite.
The sponge on T05, T80, T64 and T25 is all the same. The difference is not the sponge. It is the pimple construction. T64 has longer thinner pimples with more space between pimples so the pips give more and the rubber feels softer. T05 pimples are a little shorter, thicker, and closer together so the rubber feels harder. But even the rubber in the topsheet is the same. Just the pimple construction is different.
To the OP, I would like to ask what he means by the word "best".
I won't comment on T25; but T05, T80 and T64 are all great rubbers.
There are people whose game and style of play may work with one of them slightly better than the others. But they are all really great rubbers.
There is a video that explains decently what the difference between each one is. Once I am able to search for it, I will post it here. But it has been posted to the forum many times already.
That video should help you out a decent amount.
To sum the info up simply:
1) T05: Slower, More Spin, Higher Throw Angle.
2) T64: Faster, Less Spin, Lower Throw Angle.
3) T80: half way between T05 and T64.
So do you want a bigger arc, more spin to spin the person off the table but a little sacrifice in speed? Or do you want lower shots that don't come up as much and are faster. But with an amount of spin that is easier to counter. Or do you want to be half way in between the two extremes?
I go with slower and more spin every time. Especially since T05 is more than fast enough.
