Well, all totally different boots. Go to a bootfitters and get fitted. The booter is a 102mm.. The drop kick is a 99mm.. And I could be wrong but I believe the spk90 is a 104mm.. And all of those boots are different fits.
This, particularly DK vs SPK the fit is so incredibly different that I find it hard to believe anyone would seriously consider both of these boots. I fit SPKs, if I put on a pair of FTs with the narrow last it's painful in minutes.
