It is interesting, I spent my younger years driving armoured vehicles and landrovers, properly offroad... The most I'll do now is drive off a track to park on grass in camp sites or sailing clubs, but I do it all year round and as anyone who offroads knows tyres are the most important bit (not 4wd or suspension). So for me a set of all terrain tyres means I won't get stuck at a sailing event on a sunday night when I want to go home, or trash a grass pitch trying to get on and off. Ground clearance is not a concern, on Monday morning when I need to park in an airport car park for work being able to get under a 2m barrier is....
Some people make the lowered swamper change for the look, some with good technical reason. However I think in the two years on this site I haven't seen many people who actaully take their vehicles off road and I include myself in that statement (gravel tracks don't really count).
There's no right or wrong answer as with most things, it's down to what each person wants or needs.
