Typically I choose the Sage5 over the Para3.
Sage5 has non free-spinning hardware and a non press-fit lanyard tube, making disassembly easy, and the handle is thinner than the Para3.
Para3 has a free-spinning stand-off and press-fit lanyard tube, making disassembly difficult, and the fatter handle combined with lack of contouring makes it uncomfortable in my hand. The stock pocket clip also creates a hotspot for me (end of the clip in the rear choil area), as well as giving the knife its obvious super shallow carry.
The Lightweight version of the Para3 looks like it addresses the issues of disassembly, and has more contouring in its scales, AND has a deep carry clip that keeps the end of the clip out of the rear choil, so that would fix all of the issues for me.
Don't know if I'd take a LW Para3 over a Sage5 until I get the LW in hand.
