I think Jobs was more extraordinary as a businessman than Wozniak was as a programmer.
I don't think Carmack is a jerk so much as he's just, well, different. More like a machine than a human. I guess that could cause him to be heartless at times but he came off as fair.
Romero was important for ID's success, but as the story played out, Carmack was able to find success without Romero but Romero was not able to be successful without Carmack. Read into that as you will.
Over his life, Jobs has had a greater impact. But at the time Apple was formed, Wozniak singlehandedly designed and engineered a machine that was simply peerless. The Apple ][ made every other system on the market look like a toy for years while costing less to build. Jobs' contribution at the beginning was modest in comparison. (BTW Woz was never much of a programmer, just a killer electrical engineer.)
carmack sells middleware to other studios. id hasn't had a good game since quake 3 which is largely just a technology update of quake -- a game romero was integral to. he's a gifted programmer and i admire his work with armadillo aerospace but his post-quake accomplishments aren't much better than romero's. his biggest edge over romero is his humility. if romero had quietly released daiktana instead of endlessly promising how great it would be his reputation would be much the same as carmack's
