Having owned both crestliners and lunds. I feel I can take a crack at this question.
Dryness: I think that my crestliner was slightly dryer on any given day. Both boats will take a little spray in high winds. In large waves I give the nod to the crestliner.
Storage: This is a matter of personal opinion as far as layout and design. The fit of the lids on most of the storage seems to be a little better on the lunds. As far as the latches go I think they are fairly similar if not some of the same latches. My only complaint about the crestliner is that the rod locker lid seemed to need pushed in toward the stern to close.
Horsepower: I would say at least a 225 if you want good performance. The crestliner will be a little faster with the same horsepower than the lund.
As far as pros and cons goes I cannot really comment on that. They are both fantastic boats. This is really a ford vs. chevy type debate as it s a personal preference.
All that being said I am currently running a crestliner and have no plans of changing soon.
