Having buddy boated with Brent and Dixie, I was amazed at the storage difference on the TomCat vs the 25 Cruiser - the TomCat seems to have endless storage space (of course, with the corresponding weight penalty). I also like the flat floor and no step down into the cabin with the TomCat.
An advantage for me with the 25 Cruiser is the comfort at anchor. The TomCat with the fairly low bridge deck gets a pounding in even small chop at anchor. I have no doubt that one might get used to that, but the CD-25 doesn't have that "slap." Trailer loading is easier, and launch and retrieval can be done with less water because the CD-25 sits lower on the trailer. In 2 - 3 foot chop, the TC shines (and really moves); get into bigger, nastier waves and the CD-25 feels more traditionally solid and no "sneeze" from the bridge deck. The cabin of the CD-25 feels wider to me (not sure of the actual measurements); with the shape of the table on the CD-25, you can seat 3 reasonably comfortably at the table, where two is about it on the TomCat. It also seems to me that there is more headroom in the CD-25, but better apparent visibility out the cabin windows in the TomCat since the windows seem to be lower in comparison to the height above the cabin sole.
When we were shopping for our boat, the TC255 was a relatively new design; we liked the proven hull on the CD-25 and the $30k+ difference in price. Also, we thought the TC would be way over the towing capacity of our intended tow vehicle (a one ton chassis campervan)... as it turned out, the CD-25 was over that 8,400 pound towing capacity, so that was a moot point; also the reason we bought a diesel pickup for towing.
Both are very capable boats. If running fast is a priority, the TomCat wins hands down. If price is a factor, the CD-25 is less expensive. The rest of the differences come down to one's preferences.
Best wishes,
