Haha, it just so happens I have Galfer on the front and have had SBS Ceramic on the back.
Galfer up front have been really good, worn evenly, don't fall apart around the edges, and are very kind to the discs. I've had them on the bike for what has got to be nearly 3 years now and they are still going very strong, so I think are well worth the money.
Not sure why Calsport sell them so cheap on Ebay because they're full price on their website?
I've had sintered (semi metallic) on the rear before and they ate a brand new EBC Pro Lite disc in under a year. I will mention though I was having issues with my front at the time so was using the rear more than I should have. but even still it was like the disc was made of cheese.
From that experience alone I tried SBS Ceramic on the rear and they were much better.
I'm not keen on organic so much, especially on the rear as the extra pad dust can clog up the pistons much easier, although right now I'm using OEM Yamaha pads on the rear that were in 'like new' condition in a brake caliper I bought from another foccer.
Not entirely sure what compound they're s'posed to be, probably softer though?
Got a new set of SBS Ceramics already waiting in my top box ready to replace the rear pads when they're eventually needed.
