sgminer lacks GridSeed support, i'm more familiar with the cgminer codebase, sgminer dropped SHA suppport and baked in lots of code that makes it difficult to patch in new algorithms, i get better performance from cgminer 3.7.2 with Kalroth's tweaks, sgminer was susceptible to the client.reconnect exploit last time i checked (fixed by this commit in the latest build), R. M. Davidson's patches don't apply to sgminer out of the box, and my build would be a headache to break into pieces to migrate to sgminer + latest cgminer + misc cgminer forks for other algos. "switch to sgminer" may be a fine solution for many, but not for me today.

thanks! i'll drop a patch here when i track down the issue and get around to testing fixes.

similar in the sense that a large part of the userbase didn't like the new direction and chose to rebel against it, but this is free software. cgminer 3.7.2 is still actively improved upon, though unfortunately there's a distinct lack of collaboration among devs, (myself included. )
