In my experience, it depends on what pedals you’re running, how and where.
When you start mixing analog & digital pedals, or finicky germanium based dirt boxes with anything, those cheaper power supplies can start having weird issues especially if you’re lugging them out to random venues.
This usually comes in the form of excess noise, but not the lower pitch hiss you can commonly get from drive pedals, it’s more of a high pitched whine. Sometimes it’s just enough to be slightly annoying, sometimes it’s almost as loud as the guitar signal.
I only use the cheaper one at home, and if it doesn’t get along with a certain chain of pedals, I just run something else instead. I’ve not taken it out & been hard enough on it to comment on how durable it is. It typically works well enough for running 3-4 simple analog pedals together.
The pricey Cioks power supplies I have are built like absolute tanks. I can Velcro them to the bottom of a board & be pretty confident they’ll survive anything. With them, I can also run anything in any order with zero noise issues.
If you’re out playing gigs, the IEC cables are a lot more solid & easy to run across stages than wall warts. That’s not an issue for everyone though.
