I've done Daemonen, Kraken, Spanish Superman, Scream and Dominator.
My biggest complaint is that apart from the front row, the floorless effect is gone, and the forces don't make up for losing the ride's piece de resistance. But in the front seat, I actually think they're all really good rides. I'm not too bothered about them perhaps lacking some intensity, they're all good fun and precision engineered. Just get that front seat.
Daemonen looks strange at first glance. How can those large trains get around that tiny track, but the bulky carriages manage those inversions sublimely, no roughness despite the small margin for error.
Kraken and Spanish Superman are great aerobatic displays, I prefer Superman because of the airtime hill instead of the midcourse brakes.
Scream has an awful location, but the ride itself is quite intense and enjoyable. If it had better surroundings, it might just be my favourite.
Dominator is currently my fave. I love that it doesn't follow the traditional path of big B&Ms, and that it combines great forces with awesome hangtime.
