I think Freddered pretty much hits the nail on the head; if you want something that will do heavy off roading in addition to everything else, the Raven Tour is probably the best option. That said, if you're not going to do off-roading and don't feeled compelled to take in excess of 15Kg of luggage, I'm not yet entirely convinced the RST is a better choice given the extra cost. Taking the RST through its paces in Andalucia last year however, it coped admirably well, without throwing the bike around, with 12kg of luggage on some pretty rough trails.
IMO, Rohloff is THE choice for hills, laden or unladen for the simple reason that you know exactly where you are gearing-wise all of the time and the 44X16 ratio was more than adequate to get me up the most gruelling of climbs including Europe's highest mountain pass. What I'm really looking forward to is testing the RST on a "normal" tour (ie Brittany this May, normal roads, absence of continual mountain ascents/descents) to determine whether it's REALLY worthy of the label of a "fast" tourer! That said, the RST really does make an excellent fast commuter, even if I find myself wanting that elusive 15th gear from time to time, so I've no reason to suspect that it won't live up to my touring expecations in Britanny.
