Yeah I think we are both on similar path of thought... to me the more pieces to a circuit the greater the loss... that is just basic conductivity understanding...
Being the sample size of my experience with a CCS (Overlord only) it does exactly as intended... reduces said arcing possibility to zero.
Additionally I can add that it hits harder than the Vindicator (even though I don't own one) and I base this by a reviewer who does mech voltage drop tests on a crude built rig lol... yeah I know... ultra scientific
and he got 3.71v with .12Ω where I got 3.79v with .12Ω coils using a DMM at the terminals
Ambitionz vaper on TY does VD tests and the Overlord was like a .47VD where as the Vindy was .52... I know again .05v a whopping 3w max
Now as originally asked by Jim, if its worth the extra $20... I look at it as a way to eliminate or just about eliminate arc marks and or pitting... is there a performance advantage... probably not. But specifically to his consistency question... it could be advantageous, just not likely since he doesn't push the voltage where arcing and pitting would cause over time an uneven surface for a standard switch.
But yeah... if it comes standard (Overlord- Ruby-Arcless etc) roll with it, no choice
But if its an add-on for $X.xx probably wont be advantageous, but it could be lol
