The Zero 7 for me was part of a lightweight experiment that didn't quite go as planned. I had expected a 750g frame that ended up 800g, which was one of the reasons I sold it. But that said, it is a very sharp handling bike. What I remember most about the frame is that it requires a lot of attention in its handling. It's not forgiving to the inputs, and in return it rewards the rider with very sharp handling. I don't know what the wheelbase is but I suspect it's a touch shorter than the SR. The laminated film does a nice job of muting out vibrations while retaining a feel for the road surface.
Funny how different people ride, the handling is probably my favourite thing about my Zero.7. It's definitely very light on turn in but the frames so good at soaking up the road that it stays planted through any corner. Heck, I tried an R5CA (on Enve 3.4s even) and I prefer the Zero.7 (on Shamals day to day) just for that reason - it's simply fun.
For sprinting the CentoSR is a shade stiffer, but the Zero.7 already has fantastic power transfer and is a heck of a lot lighter, on average somewhere around half a kilo I'd say.
The Look is a very well engineered bike, but personally I don't like having to go down certain equipment routes with the way they've integrated things. I'd never buy an 695Aerolight because the Aerostem you're locked into using is made of tissue paper - the C-stem on the 695Light is a lot stronger, but still, I prefer customisation over integration. YMMV.
