I used the Bed-it (from Maine Sail) and have some experience with the off-the-shelf, RV-store variety. The PO of my previous boat (C&C 24) used the store variety and it did not stick to anything (maybe your fingers) and had to be replaced. The Bed-It, is stickier and stays sticky and flexible even after 5 years.
Of course, these are very anecdotal test results on an extremely limited sample, so YMWV.

It is my understanding that Maine Sail had Bed-It tape specially formulated. To my knowledge, he was the only source. Lots of discussions on lots of forums. All say one of two things 1) Bed It is really, absolutely better or 2) just buy any old crap from your local RV store, it's all the same. Nobody, repeat, nobody offered any definitive proof that any other butyl tape was equivalent to, equal to or better than Bed-It. Many posters swore Bed-It was indeed better. -- Dennis C.
