They went with a pill-shaped touchpad which is somewhat useless, might as well have it replaced by a button with touch-sense like the A and B button. The most notorious flaw is the stick. The stick starts to drift after ~200h of usage. There is no way to avoid this as it's by natural usage and not abuse. All you can do is RMA it and hope your new pair will last longer until they eventually start to drift as well. Valve fucked up big time with the controllers. 

Other than that fingertracking is nice but that one fucking flaw with the stick ruins it, the pill shape touchpad I can live with but the fucking stick drift is such a pain in the ass and shouldn't even happen in 2020 or on a $300 premium product.
