Hi
Form factor and sensor are 2 different issues here, personally I find the S to be a perfect size to hand carry and use it everywhere, the H is a beast for walking around and street shots, for me it would be a no go, I'm in West Africa now with the S, 35, 70 and 180 and it's manageable, the H with 3 lenses would probably be too much for me, you might be different.
Once you know what you like from the ergonomics then picking the sensor is easy, either the dreadful CCD in the 006 as voidshitter points out, I'm amazed anyone can get a decent shot out of it or the saviour of humanity, CMOS, which will turn all your photographs in to world beating works of art. You can have either in the H or the S.
If it's rubbish weather then for me the S is the only choice, not a great photograph but a quick grab shot yesterday in torrential rainy season here in Mali with the 180 on the rubbish S 006, I wouldn't use the H in these conditions but the S is no problem.
Ultimately your personal preference will dictate what you can get the most from, test, try and enjoy!
