I've used Mintex 1144 & EBC Greenstuff in my Alcon front calipers alongside standard Caterham (Ford?) rear pads. Personally I couldn't tell the difference between the two. The latest incarnation of Greenstuff appears better & now, at last, it doesn't leave too much brake dust on the wheels. Greenstuff is kind to discs as well. Not too sure what front calipers you're using but some people swear by Hawk metalic pads in standard calipers. The disc will wear rapidly but they're easy to change & cheap.
All said & done it comes down to personal preference. If you've never used Greenstuff before & you have a set lying around why not use them?
Hope this helps.
