The Space and TimeFactor pedals have more physical knobs than the H9, as have the Strymons. I think besides the price, this is an important factor for Sacred Synthesis.
I chose the Strymons for myself, but I think soundwise both manufacturers do a good job. I think the Strymons have more preset storage. If you're a fan of editing with PCs, tablets, smartphones, you better go with Eventide. Their app seems much more up to date than the PC-only application from Strymon. The Eventides have USB connection, the Strymons don't... which is not a problem, but I simply don't like to edit gear on PC over DIN-Midi.
I cannot really tell, what let me choose the Strymons over the Eventides. I think both sound fantastic. Perhaps their have been more Synth-through-Pedal-demos of the Strymons then. There's even a video of someone who plays the same setup as I: Rev2->Mobius->Timeline->BigSky... ... perhaps this is interesting for you, if you're still planning to buy a Rev2, too.
