Conventional Interweb wisdom is that Bourne fights better than Bond, but personally, I felt the Bourne rucks were just too technical/choreographed and looking back, there are some really underrated rucks in the Bond movies, but as these were filmed as chaotic fights, the technique/skill is less clear.
The Bond fights feature plenty of one-twos to the jaw, knees to the midsection, use of improvised weapons and tactical deployment of the furniture and environment, but also some real moves. Moreover, what makes these fights reasonably realistic is that they feature pretty simple techniques that anyone could be trained in, whereas the Bourne fights feature intricate, master-level MA that would require regular, intensive training.
From Russia with Love (the best Bond fight ever?):
Gun slap disarm
Jacket pull to restrict the villain's arm movements
Mount and reversal
Guillotine choke
Crazy monkey guard (sort of)
Full nelson
Rear nekkid choke to garrote
HM's Secret Service (A solid spanking from George Lazenby)
Standing arm bar
Reverse elbow
Hammer fist to kidney (ouch!)
Uppercut-downward elbow combo
Spy Who Loved Me (Moore punches like a pouffe, but not bad moves)
Double knife hand to floating ribs
Round kicks
Head control
Sean Bean fight (cant remember name of film - Brosnan was even less convincing than Moore as a fighter IMO)
Double arm pass/hammerfist to back of neck
Cross-arm lapel choke
Head butt
Standing arm bar
Quantum of Solace (Craig does the business as effectively as Connery, though the fights in Casino Royale were better, I reckon)
Clinch to headbutt
Outer wrist lock
Straight leg lock
Diamonds are Forever (excellent close-in work from Connery)
Double lapel choke
Double knife hand to floating ribs (clearly, a popular MI6 technique)
Hammer fist to back of neck
Fire extuinguisher to liver
FYI, the villain in the elevator ruck in DAF was my first MA instructor Mr Robinson - my judo teacher as a seven year old! Very big, stern chap, who held dans in judo, karate and JJ, which was pretty unusual back in the early 70s.
