Hangliding is more fun but much more hassle than paragliding. The performance is better but you would just not carry the thing on the offchance that the conditions are good. A paraglider in the boot of your car is no hassle at all. Hangliding is also a little more dificult and less intuitive. It is also harder, but not imposible, to fly on your own as it is very difficult to do a final check on the gear once you have straped in. Hangliders fly on marginally higher winds and cope better in turbulence on the other hand they also need stronger winds to ridge soar.
It is a wonderful sport but the key is to get trained properly and have the right attitude. Is like any other type of flying but the limits are very narrow. You exceed your limits (and mean yours and/or the gear) and you are taking grave risks, you stay within them and is pretty safe. You need a level head to drive for four hours to a mountain in Wales, carry your kit to the top of the mountain and then decide that you will not fly because is a couple of knots too strong. If you can do that you will be OK.
