Nah, the CB Speed Lever works (or is intended to work) in a rather different way than the bead jack. Basically it's supposed to work like a regular tire lever, but with the added ability to slide along with the tire/ rim.
While it can indeed speed up the removal of a moderately difficult tire, it won't be of much help with a properly difficult tire. And I've never had any use of the speed mounting feature at all.

The VAR tool is so-so IMO. I suppose that for someone with a modest reduction of hand strength - or poor technique, the VAR tool can even out the odds a bit. But for a well and truly stubborn tire I still prefer to reach for my set of three steel-cored, plastic clad regular tire levers.
