I recently bought a Rose Xeon RS frame set, to replace an Alibaba carbon frame. Straight swap of parts and the difference is very noticeable. In a good way, so far, but haven't gone on a > 3hr ride yet. I chose the Rose over Bowman for the included stem and seatpost, and I liked the look of the skinny seat stays.
The 2013 model is on clearance and keeps getting cheaper.
