Funny enough, this is exactly what I was deciding between. I'm not sure how you arrived at them, but I first narrowed it down to these two from TheGoodRide, where they are both Low Cost Favorites with the Rome Tour slightly edging out the K2 Raygun in their ratings system. I commenced to do additional research, part of which led me here. This is where I learned that most forum goers seem to feel like TheGoodRide is a bogus reviews website.
I spread out my search more and saw tons of good things about the K2 Raygun... on the other hand, reviews for the Rome Tour were strangely absent. Aside from TheGoodRide, I could not find reviews for the Rome Tour among any of the typical sales channels (evo, dogfunk, altrec, etc.) or many of the review sites. There was a blurb on snowboard-review.com, a few videos on YouTube, but nothing on Angry Snowboarder, nothing on Board Reviews, and nothing on this site.
In the end, I ended up getting the K2 Raygun simply based on the number of positive user reviews. One caveat though... I noticed the warranty on the K2 Raygun was 1 year, while the warranty on the Rome Tour was for 2 years.
I also did price research... for the Rome Tour, you can get a brand new one for $240 on evo.com or a blem for $200 on there as well. With the Raygun, you can get it for $230 on altrec.com with the springski discount code, but they only have limited sizes. I was not lucky and ended up having to buy the Raygun from Evo.com for $260.
I know this doesn't answer your question directly, but hopefully it helps at least a little.
