Areed, please tell us what you actually prefer. I've only skied the bridge, so I'll tell you what I think of it with regards to your list of adjectives.
Im 175m, 70kg (think thats 165lbs?), and I mainly ski off piste terrain in the Alps. For me the bridge at 179cm is able to handle most depths of powder just fine and is a lot of fun to ski, though its not going to be great for really wide powder turns.
Ive not skied it much on freshly groomed runs, but my experience was very pleseant, and it is perfectly capable of carving GS sized turns.
My problems with the bridge come with severly tracked, deep powder, where Ive always felt like the ski gets knocked around too much, which Id put down to the fact that it is quite soft.
Likewise, cut up, scraped to s**t groomers that have started to feature irregular bumps and some ice etc. arent much fun either, Ive found the ski to be a lot of work in these conditions as its a bit of a struggle to make full use of the edge at reasonably low speeds dictated by bumps. They wont feel stable on this type of snow.
The problem with the cut up groomers Id put down to two things, my fatigue (generally only end up on these after a full day of powder, hiking etc.), and the fact that you cant expect great performance of a ski in this width on poor piste conditions.
The bridge certainly *is* very playful
(excellent tree ski), has great manouverability (full rocker does make things easier), but like Ive said, it does have stability issues with the more extreme ends of cut up groomers and very tracked out deep powder. All other forms of crud it performs really well in.
