I had an ARE on my Tundra and it did a good job. I did not leak, fit well, etc.
As far as soft toppers go, they are nice in that they are easy to remove. I have not owned one, but I happened to be Boulder a year or so ago and checked out the SoftTopper. VERY well built. My only concern would be wind noise, but apparently it is not too bad.
