Not that I have much time, but I did the following for you. And I could not get the stats from BFGMiner after the q because it just ABENDs when I quit. ABEND=Abnormal End, I am old IBM Mainframer programer (have had a email address since 1969).
So here is copy and past of the last of BFGMiner=

I haven't diagnosed for differences, and I currently don't have the time since one of them is working. The box is a ASUS Sabertooth 990FX r2, 32 GBytes of RAM, Phenom II x8 @4.02 Ghz, running Windows Server 2012. The box is part of my web hosting business. The GPU is a R7 260x. Since you asked I gave it to you.
What was hashing with a passion on Scrypt was not so productive on BGMiner, apparently. Not very scientific, I just looked at accepted per minute.
Do you have time to be scientific? If so:
What hardware are you using?
What arguments are you launching BFGMiner with?
What arguments are you launching SGMiner with?
Can you run each for 15 minutes, then hit Q, and then Copy & Paste the summary here?
