I gotta chime in now...
I own a 1979 Oday 25, keep her on a trailer. Luckily, we now keep her at a marina with the mast up. Can be hooked up and in the water in 10 minutes. Prior to moving to the marina, we kept her dry stored with the mast down. We had to raise the mast every time we went for a sail. It got to be too much of a hassle, even though we had it down to a science and could be in the water in about 40 minutes once we got to the ramp. I really like the Oday, but, I am biased. She is super sturdy in the water, points well and the accommodations fit my family well. We have sailed and been comfortable for a week at a time. I must say, we are tent campers too. So, we don't need an air conditioned camper to sleep well. I have been on Soling42's boat, it is very nice. It is very fast, and I have been jealous as to how close he can get to the beach with his pop up rudder. It is very nice. His boat is faster than mine too. That being said, he is a better sailor than me too. Realistically, if you are truly choosing between the two, either are good. You will be happy with either choice. But, depending on what you are trailering with, having the dumpable ballast is very nice. The Oday has 2000 pounds of lead in her belly, and your gas gauge knows when you are pulling her.
