The PDWs are good, I have a set of both the thin and wide versions (bought when they were £40) but the Velo Orange and GB guards are better, mostly due the rolled edges giving much better water retention thn the PDWs.
As always, proper fitting is the key to longevity and function, and the GB and VO guards ideally need either additional stays or rack mounting to be properly robust. The PDw are a bit thicker Alu and seem to dodge this requirement to some degree…
VO or GB for me, doubly so now that the PDWs have gone up in price, but as Jameso says, you can save the cost of the guards in wear an tear on a drivetrain in pretty short order, let alone the comfort of actually staying dry!
