Can't speak for OP, but I've found that staggered layouts are rather non-standardized when it comes to the severity of the slant. As a consequence, my muscle memory is all over the place when touch typing, especially for the third row (ZXCVBN).

Ortholinears, of course, are all exactly the same, which lets me type with more confidence. I don't type any faster, but I do suffer fewer typos for words that require multiple row switches.

Yeah there, in my experience, keyboards can come with generally two different layouts for the bottom alpha row, it's a slight move, only about half a unit (where a unit is the width of one key), but it's significant.
