At 4033 is a very good all-purpose mic. The ksm32 is a great all-purpose mic.
The 4033 isn't quite as neutral (the mids are a bit more present, and the highs are boosted a little as well). The ksm32 is more natural sounding. What goes in is pretty much what comes out . . . only it does a pretty exceptional job of reproducing it, for the money, in my opinion. I might give a small nod to the 4033 strictly as a vocal mic, though.
The sm7 isn't nearly as all-purpose as the other two. It's great on most vocals as well as other ods and ends. I wouldn't consider it a particularly good kick-drum mic. I would actually highly advise against using it as such -- I've heard a few people mention the capsule can become damaged over time after prolonged use without a windscreen.
