I'd take an SF over an SO ANY DAY of the week because it HAS the traveler in the cockpit, so I can reach it while at the wheel/tiller. Winches are also near me etc. The SO models have the main traveler on the cabin top, so no way to reach it and dump the main from the wheel/tiller of that model.
Also the SF37 in comparison to the SO and other SF models, has a lead keel, some will consider that to be better than an iron one. 6 and 1/2 dozen or another in my book.
BUT< reality is, ANY boat can be made to SH easy enough. Some will be easier, or are already more or less ready to go. The how you vs I set them up will also be different. With Jeanneau's, I'll take an SF, or my older Arcadia BECAUSE the main traveler is IN the cockpit!
She drives me boat,
I drives me dinghy!
