I have used both the JET JWTS-10JF and the Ridgid TS3650 rather extensively lately... I think the JET has a power advantage over the Ridgid. I say this having ripped some pretty thick maple on both saws, the Ridgid seemed to bog down more, and that was using exactly the same blade (Freud glue-line rip) actually, the motor even looks smaller than my JET, but they are rated the same. I remember reading somewhere, in one the WW mags, that they felt the JET is rated somewhat conservatively at 1.5 hp. I do know that it would regularly pop a 15 amp breaker in my shop.... but that circuit was shared with some other things in the house, and that it has blown (on start-up) a 20 amp breaker once.
that being said, the Ridgid has a 36" fence (which can actually be stretched to 37.5 in a pinch - there is good suppport for both ends of the fence out there) while the JET has a 30", and the BORG's saw has more cast iron on the top (even with the open webbing), and that GREAT mobile base that can only be had with that saw now.
neither one has great dust collection, though the Ridgid does have a shroud around the blade that helps somewhat.
Hope this input helps!
