They are more complicated on the inside, which means even before flight, there are a lot things to check over..batteries, fuel, air systems, start gas, etc etc etc. You can't just "fuel 'n fly" like a sport plane, so it takes a little more discipline on the front end. An overlooked item - like an open fuel valve - can cause a pretty expensive fire.
Flying is the easy part. No propwash to mess up the air going over the tail, so it is a cleaner type of power - and you don't have to fly fast until you are ready. There are a lot of jets that happily stooge around under a hundred mph at part throttle..... and there is an incredible amount of power available at the top half of your throttle stick.

Landing though, is where you earn your stirpes. Between your gear pass and touch down, there is a lot of energy to bleed off. Flaps, speed brakes, and long runways help - a lot! But practice makes perfect.....the more you do it, the easier it becomes...

Best thing is to go to a jet rally..watch, take pictures, and talk to the pilots....who are generally a pretty outgoing group, and happy to talk about their jets......(although, you have to catch them when they are not busy....)
