Cool, though my ears can't be trusted to hear much difference.
Anyway, for $25/mike, I'm not so interested in comparisons.
Do they feel like they will survive more than one gig? A dozen?
Do they hiss, sizzle, rattle, clank?
Do they do anything awful to the sound? Is that ~9KHz ring really a few dB or is the published curve "smoothed"? I don't consider the far-field bass slope, -10dB at 50Hz, a fault in a low-price mike that may be used close; is the published curve roughly right and can it be semi-corrected with mild EQ?
Is the self-hiss level low in a quiet room?
Is the buzz level low when you drape the cable over a Fender amp? (I doubt the mikes are really balanced output, but if not too unbalanced and fairly low-Z, then buzz may be manageable.)
If you put the two mikes close together and plug one to each ear, does the image sit near the center or are they poorly matched? If the match can be fixed with a few dB of gain or balance control, that's fine; if you can't get a narrow mono image with just gain adjustment then some types of stereo recording get goofy.
