I have the SR.
However it is my first Shoei and first “high end” helmet, so I really have nothing to base a good comparison on.
I have no complaints and really like it.
I ride with sunglasses and they do not cause any discomfort or annoyance.
I chose it over the 1200 for a couple reasons:
The SR offers the same safety standards as the 1200 but the lower price is due to lesser premium type features (although the SR still offers plenty in these categories, just a step down from the 1200, but still much better than most low/mid-price helmets); i.e. - interior comfort, noise levels, venting.
-Field of view.
According to the reviews I read/watched the 1200 has a smaller visor that is positioned higher up. It is optimized on sport bikes when in a full tuck. When riding in an upright position, you have to point your head down more, instead of just your eyes, to view your gauges/controls.
The SR has a visor position that is more optimal for upright seating positions. I don’t have to move my head at all when looking down at my dash.
