I do like those, but don't want dedicated drivers for everything. I don't have the space or desire for a massive rack of drivers like you have (both a preference, and for portability).
So there are two reasons to use an extender. 1) you need the extra length because of clearance, in which case yes low profile is good. 2) for ergonomics. I very, very frequently use medium to long extensions just to get the tool to a more comfortable working position. It also gives me something to grab with my other hand to brace from when breaking loose or torqueing something down, and something to spin the screw off once broken loose (hence wanting a spinner handle). I rarely DON'T use an extension.
I have some cheap Companion extensions just like those Snap Ons with the dual engagement wobble/rigid tip, but they also have knurling on the shaft which is nice. Surprisingly, they have held up fine to a LOT of use and abuse. My guess is that they are not quite as rigid as the expensive ones when in the "rigid" mode but I have a variety of standard ones laying around too.
