Clipless Pedals List

Do people find Keo Max pedals to be any better than regular Keos?

Keo Plus - 35 squid on offer from Ribble.

Keo Max - 70+ nuggets. Seems a lot for cosmetic improvements?

Keo Blades are on the pricey side so I'm choosing between;
Keo Classic,
Keo Plus,
Keo Max

Are there other pedals worth looking into, or have Look got it sewn up?

Probably a bit late, but I'm a convert to SPD-SL over Keos. Cleats and pedals way more durable, and the tension can be ratcheted up higher than Keos. No real difference between 105 and Ultegra pedals bar the finish and a little bit of weight, not tried the Dura-Ace ones. Top tip - go to Evans and get them to price match Ribble on the 105s for about 35 quids
