I've always used the plain roll of foam for sill sealer. It's a pain since it is nothing more that closed cell foam with very little backbone to hold it in place. Now, there's a new sherrif in (my) town.
I am sold on this stuff. It's a sill sealer made by Protecto Wrap. You experienced construction guys are likely well aware of it.

Since I had alot to do with finishing the top of our concrete stem walls, and the surface may have been less than perfectly consistent, I wanted to make sure I used the best sill sealer product available. That's when I discovered Protecto Wrap. For the record, I will likely be using their window seal tape, also.
Anyway, this stuff is in a roll 5-1/2" x 25' long. The closed cell foam is 3/8" thick and it has this thick, flexible, rubbery, sticky black adhesive coating on one side with a wax paper protector. Man, does it stick. When it's a little warm from the sun, keep your fingers away or you'll be pulling hard. The beauty is two fold: The seal at the top of the foundation stem wall is complete AND it stays where you put it as you roll it out. When it comes time to stand up and set the wall, and you have to pound it this way or that for alignment, the sill sealer will not move....period.
