IME it’s completely transparent. You load up your suica and you’re off.
The issue’s it’s a bit too transparent: and after a while you realise that your suica is emptying unexpectedly fast, because you’re paying (and resetting your trip counter) every time you pass a gate, and that you probably shouldn’t blindly follow western trip system because you want to limit network switches, at which point you run into the issue that the resources for that are mostly in Japanese.
Then it depends how much the overhead is and how much you care.
