That is not what I said.
I believe Without the drilling capability Movento guides with wood boxes are more efficient.
Of course you are free to disagree 
Well, ya kinda did………buttressed by your comment on “the wood boxes are more efficient “
So yea, I disagree and think you’re plain mistaken that wood drawers are more efficient than a metal box system if you’re doing both with minimal tooling.
Might be able to concede that you could assemble a wooden box more efficiently
IF you bought pre-finished material , and butt jointed the corners with glue and nails and then nailed on the bottoms too. But I’d still wager some money I could find someone faster with a metal box system.
If you have to machine any kind of joint : dowel, domino, drawer lock , finger joint and especially dovetail - you’re gonna lose the race every single time with typical hand tools powered or not.
