I would argue ONLY advantage GGG has is Power...

RING MAGAZINE HEAD-TO-HEAD ANALYSIS

THE KEYS

HANDSPEED
Canelo has very quick fists and releases strong combinations when an opponent is trapped against the ropes. Golovkin is more about timing than speed, although he is far from slow.
CANELO ++++
GOLOVKIN +++½

ENDURANCE
Two very durable athletes. Julio Cesar Chavez Jr., at 164.5 pounds, couldn’t slow Canelo down in May. Jacobs landed plenty of shots on Golovkin, who maintained his poise through 12 hard rounds.
CANELO ++++
GOLOVKIN ++++

FOOTWORK
Both men are aggressive and movement is not a priority. However, Golovkin is brilliant at cutting off the ring and can create panic without throwing a punch. Canelo is very adept at using his feet to position himself for counterpunching opportunities.
CANELO ++++
GOLOVKIN ++++½

POWER (LEAD HAND)
Golovkin has 33 knockouts in 37 wins. That’s an 89 percent knockout ratio, and that power is evenly distributed in both hands. Canelo can punch but cannot match GGG. No middleweight can.
CANELO ++++½
GOLOVKIN +++++

POWER (TRAIL HAND) See POWER (LEAD HAND)
CANELO ++++½
GOLOVKIN +++++

JAB
Golovkin uses the jab to set up crushing combinations, and he can also use it to keep powerful fighters at bay, as evidenced in his bout with David Lemieux. Canelo works well off a strong jab, but Golovkin is more adept at controlling distance with that shot.
CANELO ++++
GOLOVKIN +++++

HOOK
Both fighters have terrific technique on the hook – with either hand. CANELO ++++½
GOLOVKIN ++++½

ABILITY TO SLIP AND BLOCK
Canelo’s defensive timing has improved dramatically. His head movement against Miguel Cotto was very impressive and allowed him to set up terrific counterpunches against an elite opponent. Golovkin is easier to hit and has the tendency to back off in straight lines.
CANELO ++++½
GOLOVKIN +++½

PHYSICAL CONDITION
Canelo, at 26 years old, is at the absolute peak of his physical conditioning. Golovkin is 35 but he is superbly trained and a quality athlete.
CANELO ++++½
GOLOVKIN ++++½

POISE AND ABILITY TO COPE WITH EXTERNAL PRESSURES
Both fighters are superb professionals. Canelo’s mental strength belies his years and his ability to improve following the defeat to Mayweather has been impressive. Golovkin is all business.
CANELO ++++½
GOLOVKIN ++++½

KILLER INSTINCT
If either of these champions has you on the hook, don’t make any plans. The slightest sign of weakness will be ruthlessly exploited. No mercy.
CANELO ++++½
GOLOVKIN +++++

INTELLIGENCE AND STRATEGIC DEXTERITY
Although there has been significant improvement in is overall game, Canelo had no idea how to cope with Mayweather. There was no significant change in his game plan across 12 one-sided rounds. Golovkin struggled with Jacobs in the second half of their fight and came close to losing.
CANELO ++++
GOLOVKIN ++++

EXPERIENCE Canelo has mixed with the better opposition as a professional but Golovkin’s amateur pedigree and long title reign make up for that.
CANELO ++++½
GOLOVKIN ++++½

BODY PUNCHING Golovkin cracked two of Matthew Macklin’s ribs with a single left hook to the body. Canelo almost broke Liam Smith in half with the same shot. Body snatchers of the highest quality.
CANELO ++++½
GOLOVKIN ++++½

INFIGHTING SKILLS
If you have any sense, you shouldn’t be inside with Golovkin. For that reason, he rarely gets a chance to display his infighting skills. This is also not an area of strength for Canelo, who enjoys long and mid-range combat.
CANELO +++½
GOLOVKIN +++½

QUALITY OF OPPONENTS
Canelo, despite being a lot younger, has better names on his resume. Shane Mosley, Mayweather, Cotto, Lara and Austin Trout trump Jacobs, Lemieux, Martin Murray, Kell Brook and Willie Monroe Jr.
CANELO ++++½
GOLOVKIN +++½

CHIN AND RESILIENCE
Canelo takes punishment very well. When the much bigger Chavez Jr. did manage to land a punch, it had zero impact. Golovkin took his licks against Jacobs and showed no ill effects.
CANELO ++++
GOLOVKIN ++++½

CROSS/UPPERCUT
Canelo’s cross is a quickly loaded and powerful punch, and his uppercuts, particularly on the counter, are terrific. Golovkin’s cross, as you would expect, is lethal but the edge on the uppercut goes to the younger man.
CANELO ++++½
GOLOVKIN ++++½

ATHLETICISM
Canelo appears to have superior hand speed and relies on razor-sharp reflexes for defense. Golovkin makes up for any deficiencies in those departments with anticipation and timing.
CANELO ++++
GOLOVKIN +++½

CORNER
Eddy Reynoso has developed Canelo brilliantly over the last three years or so. The emphasis on defense and sharp counterpunching has worked wonders in the ring. Abel Sanchez is beyond reproach as a coach, and his record with Golovkin speaks for itself.
CANELO ++++½
GOLOVKIN ++++½

TOTALS: ALVAREZ: 85½ (single category average: 4.28) GOLOVKIN: 86 (single category average: 4.30)

 

Yeah I don't know why they rate it that high. Oscar probably had a word in their ear.
