To be honest Nick, after using Crank Brothers, Time and Shimano Pedals over the last few years, I would always go for the Shimano. I find them easier to click into/out of & easy to tune.
I actually dislike crankbrothers pedals. I have a set of eggbeaters that I find difficult to locate on, and for the odd occaision where I want to unclip but still keep contact with the pedal I find them seriously difficult to place my foot on.
I have also had a set of candys which were easier to engage with. They came as OEM equip on my shop purchased epic (200
the bearings lasted less than 10 rides...probably under 200 miles before they felt distinctly knackered.
If you have bad knees, I think I have seen a lot of comment from people who find the Time pedals/cleats a lot more comfortable to use.
