I have both.
The BK7 is a superior cutting tool (by far), even though I reprofiled the edge on my SRK as thin as I could get it.
If I asbolutely knew I was going to be prying HARD with a knife, I'd go with the SRK. If it's intended to be a cutting, slicing, and chopping tool, I'd go with the BK7 without hesitation.
I'd also get the micarta replacement stocks for the BK7. The original grip is both too big and too slippery (the latter can be fixed with some sandpaper).
