Hi,
Between the two, I would definately say Cold Sweat - especially if you have a Miracle Man bridge.
The Stormy Monday is open and clear sounding but not overtly bright and it's Alnico II magnet and wind make it pleasantly loose in the bass and sweet in the treble, instead of definitive and focused. I love my Stormy Mondays, but they need another low to moderate pickup in the bridge I.M.O and I feel will not meet your specific expectations.
I find the Stormy Monday best suited to Soul and Blues styles, with occasional excursions into Gary Moore territory.
So, for power balance and focus - I'd go with the Cold Sweats ...
:D
