sailed both, then looked at the 36CC (which had the same hull as the going to be 361)...the first was absolutely faster and easier to sail...the 393 had better interior and "could" be made to sail fast.
My wife loved the 36CC, and with the same hull as the up coming 361 she would move right along as well...so we compromised on the 36CC and loved everything about her. Even now, two boats later we talked about downsizing back to the 36CC...it is that good.
All that being said, if you can do without the aft full size berth, the First's are awesome and for some reason seem to be a bit less expensive...
Best of luck, and either would be great!
