I have a GH3382QD. It’s stable, doesn’t creep and is pleasant and smooth to use. The arca base seems very compatible with the plates and L brackets I’ve used it with. I’m not entirely persuaded it’s any better than the Manfrotto head I used previously - certainly not in terms of order of cost, but it’s a fair chunk lighter. My only gripe is the pan head adjustment screw isn’t captive (it can be undone completely) and thus I lost it on its second outing, but at least you can get all the spares!
