For 'extencive' oceancrossing and varying conditions the build-up of the boat is essential.
Those You mentioned use in general a 'thin' outer hull and innerliner module.
Unfortunaletly quite some of them end up as 'jelly boats' after some heavy weather when the innerliner starts separating from the hull! And believe that You may avoide 25+ is a dream!
I did my 'trip' in a Jeanneau SO37, and one of the reson a chose that boat was its modern design, but traditional build up. Old type solid hull, full stringers, shrouds attached directly to hull-frames etc. A good 'test' might be to rent a 3-5 year old boat that has been 'out there' and se what it is like after the pounding! I think that might eliminate some of those You have mentioned without me naming them as 'not suitable'.
My 'test report' might give You an idea and some hints.
