I don't own or have ever used a turbo-less pad, so your response has me wondering - do they have a different type of dpad to the more ubiquitous turbo versions?
I think they're exactly the same in the turbo and non-turbo versions; the fact is that I don't own a turbo version of it
Among all my controllers - I also have a 3-button, 6-button and some Hori, not a single one that originally came with a console - I prefer to use the turboless one because its d-pad feels better, the others are a little "loosier" than it.
