I hope that I can help a little, as I have both Cold Sweat bridge and Miracle Man (actually Miracle Man is my favorite pickup and have 2 of them in two guitars), but anyway...
In my opinion Miracle Man is a metal pickup but not extreme one and not super modern but still..., when Cold Sweat shines more in rock/hard rock territory being more versatile I think.
Cold Sweat is definitely more polite, tamed has better string separation and better cleans. Both good at leads and both great rhythm pickups while Miracle Man is hotter, more aggressive and bigger. Some people call Cold Sweat bridge as 'screamer' on this forum but maybe it`s my setup maybe guitar but my Cold Sweat is rather polite, tamed and 'polished' sounding.
I also have Miracle Man neck and suprisingly it`s really good neck pickup, it reminds me a lot of Zakk Wylde neck tone (for some reason neck model in my opinion is closer to Zakk`s sound than a bridge...)
I`m familiar with Cold Sweat neck too, as I have it in another guitar (paired with CBomb) and think that CS neck will work perfectly with MM bridge.
Summing up if I would want more 'classic', more versatile and more polite sounding pickup which shines in rock/hard rock territory I would go for CS, metal ect definitely Miracle Man
but... I would have to be left with only one pickup I would definitely choose Miracle Man.
Best Regards,
