I would say about the same as the T-1.

Even though the T-1 did not have the FSX k-b , you will find that the S900 key-bed is not as good as the T-1.

Rubber buttons and poor control surfaces too.

Sound is Great ! Maybe better than the T-1 .

The S900 does have some of the T-2`s SA voices.

Good luck !
