Which rubber has better of control and speed for a close to table shakehand looper?

I don't recall how Bryce plays - I have used it some two years ago. Few months ago, I have tried Sriver FX.

I have tried Donic Coppa Platinum. That is a good looping rubber. The Gold has a little harder sponge, so you can get points fast if you can execute loop kill.

I have not played with Donic F2 but I have tried with my friend's Bryce & I used the Shriver.

My friend's feedback on the Donic F2 is for the player who in the past has used the traditional spin elasticated rubber, but without the use of speed glue. It is slightly faster than the DONIC F3 and slower than Donic F1. If use speed glue but still maintain good control, the DONIC DESTO F2 will be ideal.

As for Bryce, I find that the speed & spin is great for a medium half loop, even the touch feels good too. The durability of Bryce is also good, and is value for money. IMO, I consider it as not expensive if I look at cost per year rather than cost per sheet.

Shriver - This is a good rubber for fast drive / looping strokes. Not so much on control (for me, though).

I've heard that high rated players speed glue Bryce and Sriver. I have heard that Butterfly has come up with the speed glue versions of these rubbers.

Most high rated players speed glue every rubber they can get their hands on.

With the ban on speed glue, most players will seek alternatives.

BTW, I heard that Andro brand of rubbers has the "speed glue effect" but without applying the speed glue. Is this true?

In the race of releasing rubbers with speed glue effect, I think German manufactures have done well. I have heard that Andro has some rubbers out there but I have not tried any of their product.

I was satisfied by DONIC, JOOLA, XIOM and TSP products that I have used before. They all have products with speed glue effect.

I have tried Donic F2 but out of Sriver and Bryce I would choose Bryce for Looping.
Sriver actually is a more all round rubber and bryce is faster and more spinny, but less control.

Does Bryce has a softer sponge? When you loop, does the ball go deep into the rubber?

Nope not alot.

Bryce has a hard sponge. Basically i'd go with Sriver. Bryce and F2 are good fast rubbers but with Sriver, you get speed and control. Though, I notice Sriver easily lose it's tackiness.
