Not a TP but I've flown microlights of both styles:
AX3 - 50hp low aspect ratio 390kg MTWA
Chevvron 2-32 - 32hp high aspect ratio 390kg MTWA
The AX3 was much more fun to fly as it's shorter wingspan allowed more responsive roll rates; in comparison the Chevvron roll rate was much slower to the point of being like a Wessex ie move the stick and wait for the response!
The Chevvron encountered ground effect when landing even with flaps or airbrakes (it had three types of wing, one of them clean and the others with either flaps or trailing edge brakes) but the AX3 was very easy to land with neither of these; I used to demonstrate how you could level off at about 2 feet and it would land itself when ready. The AX3 was also less prone to gust reaction and much easier to handle in a crosswind. Having said all that, the Chevvron had a much higher cruising speed in spite of lower power, and hence was a better cross country machine, especially if you climbed to about 4 or 5 thousand.
