I can't speak to the 25, but a friend has a Southern Cross 23. The S.C. 23 is similar in size, weight, and ride to my Dad's 21SE Parker. I'd take the 23SE parker over the S.C. 23 any day. My Friend's S.C. 23 just got delivered this year after a long wait. I think S.C. are still fairly low production numbers.
The S.C. 23 is a modified V hull, and I believe the 25 is too. The pricing on the S.C. boats is pretty attractive, so even though I imagine it's less boat than the 25SE Parker it's probably still a good boat and a good value.
