I know you are wanting information on the CC only but here is my experience. It really depends on what you are using it for and where you will be using it the most often. I had a 2320, which is the same hull as the 2300 DV CC. It was a really nice boat but it's strength wasn't necessarily the ride. It wasn't bad at all however I have been on smoother riding 23' boats (like the older SeaCrafts). I have also been on several 2520, both DV and MV boats. It's not an apples to apples comparison because the 25' Parkers have a 9.5' beam and their 23' boats have an 8.5' beam. Where I boat/fish, I would have preferred to have the MV because we do a lot of trolling, drifting and putting around. My 23' DV would definitely do fine but it did sway/rock back in forth quite a bit more than both the 25' DV or MV. In fact, for my type of fishing/boating the 25' MV was the most comfortable. I fish the Chesapeake Bay, Potomac River, and their tributaries. I never took my boats off shore (Ocean). Now the Chesapeake can get very snotty but it's different than the ocean. Most of the time the Bay would be swells, 2-4' waves spread apart (unless a storm or wind storm would come up). For me, the 9.5' beam on the MV hull was a better designed boat for my area of boating than the 25' DV, and much better than the 23' DV, at least how I used.
As for fuel burn, the parker 23' DV hull uses a lot of fuel. It's a heavy boat and moves a lot of water compared to a MV. I loved the 2320 but a better choice for me would have been the 25' MV. I would loved to own a 25SE one day but will probably (eventually) get a 23 SE. The Parker 25' boats are big boats and the 23' is just easier to handle when you keep your boat out of the water.
I guess we really would need to know where you are boating and how you predominantly use your boat to help anymore than what you've read so far.
