I only have experience of the XT.
It's all down to individual preferences and it took me a lot of patience and experimentation to find the sweet spot for my usage.
1.2 will work really well IF you have off route recalculation off and like to find your own way back onto your route if you deviate. For many this is the perfect choice.
I prefer 1.1 because if I go off route I like the XT to re route me. I often ride roads where an unexpected diversion comes into play and I'm not always that bothered if I'm not riding my route inch by inch perfect the way i planned it!
Will, good overall analysis. The only thing I'd add regarding 1.2 is that (from my testing and experience) you don't necessarily have to find your own way back due to a deviation. With 1.2 if you go off-route with recalculate on, the XT will try to turn you around to the point where you went off-route to continue. It's not a complete route recalculate, just an annoying series of instructions to go back to the deviation point. And if you deviate for the purpose of stopping somewhere not on the route, you can select "Closest Entry Point" when starting things back up. Again, a global recalculation is not triggered.
The problem with 1.2 is performing any action that actually triggers a complete route recalculation. The major trigger I found for complete recalculation is adding a via (stopping) point as part of performing "Search" or "Up Ahead" while the riding. The absence of 1.1 shaping points completely destroys the route.
I go back-and-forth between 1.1 and 1.2 depending on the nature of a specific route. They both have their pros-and-cons. Choice is good.....
