KAP,
I used to use pocket hole screws for a long time, and I was always frustrated how they'd "walk" on me, especially on face frames. My reveals would get all funky. Then, I'd always have to put a cover strip on over the oblong holes on the inside of the cabinets. I was kind of particular how the insides looked and those Kreg plugs were a pain.
All P system connectors (including Tenso) are self-aligning, but also allow lateral adjustment just prior to final clamping. Being totally invisible is in itself a huge advantage. You can also set up a Zeta very easily to position the connectors so that you'll achieve a fixed reveal on your FF overhang.
Yes, the purpose of the Tenso is to take the place of a clamp, and it's recommended that you always use adhesive if you're installing a permanent face frame or building a cabinet box with Tenso. However, you could accomplish the same thing with the Clamex connector and not use glue (200 lbs. clamping force). See video below. Some applications you could use Tenso without glue are valances, scribes, toe kicks, etc. As Harold mentions, once guys get the system in their hands they start finding all kinds of different ways to use it.
In addition to Swiss build quality and unmatched tolerances, Lamello will be introducing at least one new P system connector per year (this year, there were 2). So, there's a lot in can do now and it won't remain static.
Contact me at the MA office, I'd be glad to help you out directly too. 781.585.4364 x.206
