I'm currently riding both bikes as my first and second option (around 4K km on the Look 695 SR (XL), 1K on the Storck (59 cm)). In my opinion the bikes feel very different despite ridden in similar setups.
The Look is very comfortable on the rear (riding the grey elastomer in the Ergo seatpost) and adequately stiff on the front. The fork feels very direct but also somewhat uncomfortable not so say harsh. The overall ride quality is nevertheless decent. The bike feels very responsive, agile, light and delivers a good road feel being comfortable the same time. I frequently use the bike for longer outings (also in the Alps) and never felt beaten up after 5+ hours in the saddle.
On the downside, the frame/fork/drivetrain/stem system integration tends to be noisy (despite being properly set up). Replacing even small (proprietary) parts (e.g. chain ring bolts) can turn out to be expensive as well (I paid 80 € for 6 of those bolts). In terms of ride qualities, descending doesn't seem to be the bike biggest strength, though still being a lot better than my Cervélo S1 in that area.
To sum it up: The Look is a great allrounder without real weaknesses. But it isn't as spectacular of a ride than the looks and price tag may imply. I mainly use it for long training rides.
The Storck is somehow the exact opposite. It looks like a boring dentist's bike but is in fact a real thoroughbred. Stiffness is king in all areas with comfort just being ok (I use the Storck 185 seatpost which is just very good and saves the Fenomalist from being uncomfortable). Descending is just phenomenal (mainly thanks to head tube stiffness you feel like riding on rails), as is ascending (it's still very light!). The overall feel is more "stable" than the Look and it doesn't feel as agile. As I just have 1K km on the bike, I may still feel some new bike sensations, but I guess that the Storck will be my goto race bike and used when the hard efforts are on schedule.
I'd recommend both bikes anytime, though. As the Storck is significantly cheaper than the Look in mainland Europe, I'd probably go for the Storck if I had to choose.
Get a bicycle. You will certainly not regret it, if you live.
