a) Identifying them
b) Telling me which ones are best (if there's any difference).
The first contender *might* be off an RS250, or an NSR250R, or who knows what. Pictures are outside (left pic) - inside (right pic):
Then the second one, here, is likely to be off a regular NSR250R, again, inside - outside are left -right pictures respectively.
And finally these I am pretty sure are stock MC28 SE calipers:
