We took a sea trial in both models, RF246 & CD25, before we decided which to put our $$ in. Like others, we too, tracked both for some time.
Hull differences are obvious and the ride reflects this; from the shallow draft to the 'V', etc., so I won't go there.
A noted difference was mentioned for some one 6' tall, or more. I'm 6'2" and found I could just touch the inside bulkheads of the RF246 and had to stoop down to enter more when entering the RF246, with the standard top. The inside width of the CD25 is more and the inside height is also more.
While on the sea trial of the RF246 we had an occassion to encounter [~3']broadside wakes. The RF246 handled well, but we had the port side door open. My wife was sitting on the seat by the door and thought she was going to fall out. There weren't any screens in the door to help ventillation, so it was left open. This could be corrected, I'm sure, and safety netting of some sort would meet most needs like there are on some sailing vessel handrails setups.
We felt we got more 'bang-for-the-buck' with the CD25 with the setup we desired on Sea Angel. AND, it is built in the U.S.A..
Either boat is a first class vessel for what they are intended for. The factory response from both companies is proactive. It still comes down to use and style, in my humble opinion and 2 cents worth.
