You are likely to get replies directly along the lines of the boat the person replying owns. They both have there pros and cons.
The size boat you are looking for and the number of people that mostly go out with you also make a difference as to what works best for you.
We typically have 6-8 people on the boat. Several of those may be kid (and no doubt there favorite place is the platform). Adults are usually hanging out in the back comfy seats (closer to the cooler I might add). Some people like to sit up front while we are cruising, but most prefer the back for comfort and talking.
