In that size range the best boat
to cross oceans will not be as comfortable as the one that works best for livaboard. Something like a Contessa 32 would be close to ideal for an ocean crossing
both make decent boats in that length. When looking at a 22 year old vessel, the prior owners maintenance
and upgrading will make more of a difference on whether or not its the right to purchase
than the model itself imho.
We have a Hunter 410, love the boat
and find it to be really well constructed throughout, but things like bilge
pumps, float switches, heads etc need constant maintenance
in either brand. I had a friend in Toronto who owned an Oceanis
351 that I spent a lot of time sailing on. It performed really well. He later sold
that boat and bought a 41+ deck salon
Hunter which was his favourite boat he ever owned/sailed.
Good luck with your search. Decide what your near term priorities are first. The best liveaboard boats in 34-35' range will not be the best offshore
boats. If you plan on leaving soon, look for a smaller passagemaker. If you plan on leaving in a few years, get a good performing boat, (both the options you suggested are) that will be a comfortable home. Just like a Jeep, a Porsche, and a Passat are all decent road vehicles. They each do one thing really well at the sacrifice of something else. Boats are no different.
