I'd worry more about E height and left border distance. In the G80 L Cherry I'm currently typing (I haven't Cherry double-shots at hand, so please confirm!), the F's have about 2mm, while the SP ESC (Fentek) is about 2.5mm tall. Cherry keys also have a left border about 1-1.2mm, while the SP has ~1.5-1.75mm, being about 0,5mm offset to the right. This looks to be the case in your pic, because the correct border left border size should be smaller than the E width, not equal. But then again, this may vary in G80 H keys.
Not every F row Cherry key is completely centered. Some are about 6mm up and down, while other seem to have a ~0,5mm deviation to the bottom.
