Apart from the EB Smarties, which wore out embarrasingly fast, I've had zero issues with both the original EB and EB Candy. Well, to be honest, maybe 1/4 of an issue, when fitting the cleats to my winter MTB shoes, which took both shims and a minute amounts of sole surgery before clip-in become clean and crisp. IME original EB are more tolerant about sole interface, but more demanding WRT positioning the foot correctly. Candys and suchlike are slightly easier to find the right position on, but they're all good.
With that said, I think both my shoes are set up with the sideways adjustable cleat.
