I think the type of girth used depends on use, I mostly trail ride, in low scrub/brush, long grasses, bush and sometimes water. My choices might be different if I mostly used groomed surfaces and wide/clear or arid trails
I use perforated neoprene, yes the horse sweats under them but I don't find the good ones stick when dry or slide when wet. Cheap skinny or badly shaped can cause issues, but that goes for any girth too.
I find any string, felt or fleece just gets full of burs, seeds and twigs. My mare also gets itchy from the (I believe) salt build up in absorbent girths if it's not carefully washed after every use.
I find leather girths to be much the same as neoprene only require more care
Pinching, rubbing and galls are related to bad design, incorrect position, poor quality or too tight/loose IMO
See what others are using who do the same type and amount of riding as you and then it's just trial and error.
