I like the Noodles, mainly for the longer and flatter ramps, though it depends what your preferences are and your reason for changing. If you do go for Noodles, you may need a shorter stem, those long ramps put the hoods a bit further forward. I swapped from a compact bar and need a 20mm shorter stem, a more traditional road bar is probably somewhere between. I haven't tried the Nitto Randonneur, but didn't get on with the similar VO ones, not sure why, just didn't get comfortable.
If you haven't already seen it - Planet X stock a good range of Nitto stuff, including two versions of Randonneur bars just to confuse.
