New to this here so I may be speaking out of turn and apologize if so. That notwithstanding you mentioned looking at the numbers but not the mission you intend to fly. You probably saw that there's a big difference is the short and unimproved field performance. The Cozy documented numbers are 3 times that of the RV and pushers are not grass and gravel friendly. However, they're both comfortable cross-country haulers and as Marc pointed out the Cozy will shine at the pump. AOPA published an article a few years back highlighting the need to evaluate mission first. I'm still working on figuring that out myself; the needs, wants, and nice to haves. Hope this helps!
