its weird im kinda with you, like most boxs i ride are tilted so its hard to greese, but when you try techy stuff they become a lot easier, and rails are oppostie always easy to mak but harder to do moves
boxes are hard to come on foward and just come off forward. its hard to just strait grind a box without comin off switch or spinning on it. Rails are just hard to slide the whole way and easier to pretzel because its easier to stop ur rotation on a rail
considering that boxes are usually a foot wide at least and rails a couple inches and for most a foot wide platform in comparison to a platform thats only a couple of inches wide is much easier to balence/stay on im going to have to pick boxes, final anwser.
but when the box is 40+ feet long and like 6 in wide it can get harder than a rail cause you cant balance. So you have to be on straight from the start
but thats a bad arguement cause boxes are deffinately easier
