I have a Jandd expedition and extreme combo. I love the expedition, and the extreme is good, but I have had a couple issues with the extreme.

First off, my bianchi volpe doesn't have mid-fork braze on bolts. That means that I have to use the accessory clamps to connect the extreme rack to my fork. Not a real problem, but I wore through a set of clamps after about 3000 miles of touring, and had to finish a long tour by zip tying the rack to my fork. I'll buy beefier clamps before touring with the extreme again.

Second problem, the extreme just barely fits my bike. It works fine with 700x28 tires, but it was too small to fit the 700x32 cyclocross tires that my bike came with originally. I have to think that this is an issue that is specific to the fork geometry of the volpe, but it might be a good idea to test fit this rack before purchasing.

And the finish on the expedition rack has become heavily scarred after years of use. But I commute every day with this rack, in addition to touring with it, so it has seen a ton of abuse. But even though my panniers have removed a lot of the finish, especially on the top of the rails, there isn't a single sign of rust. I kind of like the scuffed up look, anyway. It shows that my bike is actually getting used.
