i liked the $55 microscender better than the $66 Gibbs. i like the spare tension cables that Sherril now offers for the Micrscender; i ended up going without for a while without incident, but that is probably not best...... i remove quick pins on lanyard cams and put provided bolt/lock nut in their place.
For attatchment of the cheaper Microscender i favour extremely the $16 twisted clevis Sherrill offers, that was my slickest purchase one year, lineing that Microscender up just right and so discreetly. Now they have one for the Gibbs, that works so well.
But like/ partially because of Brian (heeeeeeeee's baaaaaaaaaaack) now i use the VT chord he recomends, lace the lanyard through the metal ring as knot tender too. Then i tie the chord right to the side D, dispensing with the cost/length/but disconnectivity options also of the carabiner. But, got used to leaving lanyard in one spot with twisted clevis, so loss of immediate repositioning/removal hasn't bothered me.
Never tried a Grillion. VT/frcition hitches adjust loaded like Grillion, cam devices aren't made to.
i really also like my lanyard with an aluminum snap.
