I think you need to define handling first , the ability to be ridden very quickly down your favorite trail ?
contentious, but i think any standard framed rigid mtb can be made to handle well ,just fit some decent tyres and make the bike fit you
so tyres are the biggest influence on handling ?
the feel or ride quality is a different matter tho , butted tubes make a bike
feel more alive and more comfortable
so frame material is the biggest influence on a bike's feel /handling
best just judging them by colour , i like polished ones best
