Basically, I agree to your agrument.
What I thought was a general idea most of the time CMOS logic should be comparatively having low power consumption compared with other technologies if we are talking about same logic functions, so actually, this question is too wide to discuss here, however, one thing is quite certain, over the past 30 years, except nowadays in very deep submicron technologies (we are not talking about leakage here), if you want to have minimal sleep mode current or standby current for a circuit, CMOS is always the best.
