Hmmm. Lets see, sage mode grants him extreme strength and resilliance. In fact sage mode is resilliant enough to take the destructive cellular side effects of rasen shuriken. As for speed I don't see it being much faster than his regular speed. As for sensing it definitely is on a whole different level from the other two forms. He was able to sense the entire war in seconds, even specifying who was doing what and was able to pin point Nagato's location easier than the best Konoha sensors. Don't forget about being able to sense the third raikage's attack, dodge it, then strike his arm hard enough to make his big, strong ass stab himself. which actually is a perfect example of Sage Mode on all three areas.
As for Kyuubi Mode. His speed and strength is definitely stronger than SM. He can basically move in a flash. He is also strong enough to lift boulders and rocks with one kyuubi chakra arm. He also was able to push a TBB through 36(?) barriers. Definitely strong. He can sense evil or killer intent, but nothing has been shown on the scale of SM.
Bijuu Mode is yet on a whole different level from KM. He was fast and strong enough to deflect five TBB in one swoop. He also whooped the snot out of five tailed beasts. I would assume that sensing in this form would be the same as KM since that type is an attribute of Kurama's jinchuuriki.
