CQC was better. There were no pointless gameplay mechanics only good for a laugh, and that's a plus to me. MGS4 gameplay suffered from other poor choices (a problem shared with MGSV).
CQC is better in MGSV, in my opinion. It is a heck of a lot less clunky (none of that "One step. Okay, now two step. Right got him on the floor. Now..." etc.), looks better, feels better, and is intuitive.
As for the bolded...
...it wouldn't be Metal Gear without them.
