If all are in the "the same condition is the biggie. (Price too of course) If they are all equal in respect to price and condition, of course their not, but "if they are",,, the Pearson and Catilinas have the best resale. The Hunters, while popular, do not seem to appeal to the eye qute like the other 2. Too "production" like. For me. The C30, because of its wide beam is a very comfy boat. A real good coastal cruiser. Their engine access is one thing I marvel at. The Pearsons, while not laid out (bellow) as well, are very sea worthy craft. Their
lines always catch the eye of us sailboat lovers. Much like a fine woman. The C30 might have the edge for customer support, but all 3 are easy to find parts, help etc. All have great followings and owners' groups. Again, the condition of older boats, how well they have been maintained, is all important. Close inspection, survey. Good luck. Looking at sailboats to buy is one of the most enjoyable pastimes I know of. Have fun.
