From personal experience porting fairly large and complicated multiplatform userspace application codebase from 32-bit to 64-bit on both Windows and Linux, I think the required effort is about the same. Linux also uses different directories and has "potentially a lot of other issues". Windows uses LLP64 rather than LP64[1] but IMO that's just different not clearly/necessarily better or worse.
