Salsa I think did it right with so many hand positions. The bars seem very large, probably one of the largest I have seen especially at 46cm size. The Garys pictured above I think are v1 which did not have much for tops, I have v2 (not in use) and they have more of a traditional road bar look.
I would also tell you to look at WTB Mountain Road Dirt Drops, I use this bar now on my "adventure bike" and find the hoods to be the MOST comfortable position. The bar comes in a standard mountain 25.4 vs a road 26 so you will need to keep that in mind on stem choice.
Please ignore the bar tape hack job.
