I have fished in them all, and currently own a zx250 Skeeter. I would say the #1 selling point is going to be the added deck space you get in the Skeeter. I was in a friends z20 last week and was amazed how narrow the boat was compared to the skeeters.

But, like a lot of people are saying, you are going to have fans of either brand. Take a ride in them, and try and fish out of them for a few hours if you can. Then you will be able to make a decision on what is right for you.
