In a match Samoa Joe would kick Umaga's ass and Samoa Joe is a way better wrestler then Umaga. Lets look at their stats shall we. First Umaga the WWE marks savior, the guy that copys of Samoa Joe, the guy that is similar to Samoa Joe but when asked by a WWE mark which is better they say Umaga by alot. These are Umaga's moves:
-Samoan Spike (Thumb thrust into opponent's neck; occasionally preceded by a lifting single arm choke, or a feint short-arm lariat)
-Flying Sausage (Top rope splash)
-Wild Samoan Drop (Body press to a Samoan drop)
-Running hip attack to the head of a seated opponent leaning against the bottom turnbuckle
-Running headbutt drop to the head of an opponent held in the tree-of-woe position
-Second-rope diving headbutt
-Turnbuckle powerbomb, usually preceded by an elevated three-quarter double-arm choke
-Giant swing, occasionally into an object such as ring steps or a barricade
-Axe handle smash
For those of you counting at home that's 9 moves, something that my little brother can do. Now let's look at the greatest wrestler to hail from Samoa, Samoa Joe:
-The Choke (ROH) / Coquina Clutch (TNA) (Rear naked choke)
-Muscle Buster
-Avalanche (second rope) Muscle Buster
-Island Driver (Sitout side powerslam or side reverse piledriver)
-Avalanche Island Driver (Second rope sitout side powerslam)
-Chimeraplex (Combination German suplex, dragon suplex, and cross-arm -German suplex)
-Samoan Elbow (Feint leg drop to elbow drop)
-C.C.S. Enzuigiri (Enzuigiri)
-Olé Kick (Running yakuza kick to the face of an opponent seated on a chair next to a guardrail, while fans chant "Olé, Olé Olé, Olé, Olé, Olé")
-Facewash
-S.T.Joe (Standing one arm side slam, a counter to a running attack)
-Backhand chop to the back of a sitting opponent / Inverted atomic drop, followed by a football kick to the chest knocking the opponent down, then bouncing off the ropes and landing on the opponent with a running knee drop
-Powerbomb with prawn hold pin, using the opponent's kickout to turn the over in to an STF, from here Joe often converts it to a crossface hold
-Repeated open hand slaps and palm strikes to the face of an opponent followed by continuous knee lifts
-Single leg running front dropkick followed by bouncing off the ropes to perform a running senton on the downed opponent
-Scoop powerslam
-Thigh hold Boston crab
-Tope suicida forearm smash
For those of you counting at home I believe that is 18 moves half of more then what Umaga has. And if those stats don't show that Samoa Joe is a better wrestler I don't know how to convince you WWE marks
