I'd say poachers. I demoed both and picked up a pair of poachers in a 177 (I'm 5'10", 140lbs and I use them for park and shitty condition all mountain days).
They are the most bomb-proof ski i've ever skied. Usually by this time in the season I would be on my third pair of skis, but my poachers are holding super strong with only a couple edge cracks and topsheet chips. I prefer a stiffer ski, and the poacher is pretty stiff for a park ski which translates to stability on rails, stomping huge jumps and stability when RIPPING shit fuck conditions, BUT are a little bit of work when going super slow into rails etc. I ski in banff alberta, so when we get snow they're not too shabby in the deep stuff but i definitely prefer my candide 3.0s. And, finally, although this shouldnt be a factor when buying skis, I LOVE the look of the tapered tip and tails. For some reason they just look amazing when they're spinning. But yeah, that's just me! Only thing I didn't like about them is while the general durability of the ski is amazing, the topsheet chips pretty easily but that doesn't affect the performance so i dont really care.
If you prefer buttering around and taking it a lil slow in the park, I'd say go with the ARVs.
