The average PPL flies differently to a military bod is because of the reason for his flight. After he's earned enough money to pay for his flying (and yours) he'll be flying for fun. The performance of their aircraft so low that any level offs might appear to be abrupt but in reality, less fierce than most military ones. Circuit shapes are the ones that the old military instructors gave us and also what other users would be expecting. "Runs & Breaks" whilst good fun are frowned on, are often illegal and would almost certainly pee of those living close the airfield. Also, with a pull-up entry speed of less than 200 Kts with a very fast PPL type aircraft, it would also be visually rather unimpressive. So they are not done. Rather amazingly, a cruise is set up by applying a both pitch and power setting, adjusting as appropriate to be "knot perfect" whilst simultaneously keeping a damn good lookout for people in green and grey aircraft burgling the circuit.
As for other differences, well it depends on who they are and what and where they fly. The wealthiest may be out in their Extra's, Malibus and Mustangs. The poorest in their microlights, the traditionalist in their Luscombs. The important bit is, they'll be there enjoying themselves, respecting other people in the the air. The biggest thing to accept is that they have the right to be there.
But I have a question. What aircraft in the RNZAF aircraft does 300kts in the circuit? ...and why?
