I've got the 25 on my GG6 which was my first purchase, when I bought my FLEX I decided to try the 10'. If I had to choose only one I would have them both 10's. When the 25 is wrapped up it is really hard to put back in he original box, and if you leave it out there is a whole lotta cord to lay next to it. I've got plugs every 6 feet in my garage and extension cords in one of each outlets. The 10 suites me better. I do like no needing needing the extension just don't like it as much as I dislike the 25 when rolled up.
