From my experience, UPB (Both SA and PCS) switches are far more reliable than Lutron. I can count on one hand the UPB failures. I'd have to take my shoes off to count the Lutron failures. I don't feel Lutron has a high failure rate but my experience indicates it is not AS reliable. The company itself on the other hand....

But I have never installed the PCS switch panel. It would probably elevate their business if they would make an actual panel and dimmer/switch "modules" like big blue does (and Vantage)

Caseta does still have limitations compared to the higher tier systems, even when combined with a control system. The most obvious are devices maximums, controlling tricky or large loads, huge properties, lack of keypad options, lack of color options, etc. The switches and dimmers also look out of place next to standard Decora switches.

Caseta is absolutely fantastic for what it is, and a freaking bargain, but if I show Caseta to a designer or architect they will typically push the client to increase the budget for a Ra2 or HWQS system.

That said, it is the first "cheap" lighting control system in which the performance meets (and even exceeds) the specs and expectations. We installed a handful of Z-wave dimmers for clients that had Z-wave door locks already and they were nightmares, pushing us to install Ra2, HWQS or nothing. Now with Caseta we have an affordable solution that we have no hesitation installing if it fits the maximum possible specifications that a project might present.

We sold around $200k in Lutron last year, and we have had some failures, but nothing compared to even the 2nd most reliable product in our lineup. We lost a Ra2 Main Repeater and a Triathlon roller shade just last week. I couldn't even remember the process to RMA products with Lutron we have used it so little.

And before we get too far off the track...to put wireless RF switches into the PCS cabinet (and yes I have installed them ....they are beasts) would be a recipe for disaster.

What's the limit on a number of Caseta dimmers in a single, C4 installation?
Is it a site limitation or a repeater (if it's even required) one?

In my own house, I still need to move few switches from UPB to C4 due to UPB's lack of fade rate adjustments.
In my home theater, I have 8 dimmers alone and I rather not drop a grand+ on C4 APDs if I can avoid it.

Can I 'assume' that I can still use C4's wireless keypad to evoke different lighting scenes on Caseta dimmers like I would with OEM'ed APDs?

???
What are you talking about? There is no lack of fade rate adjustment. I can make my Pulseworx dimmers go anywhere from instantaneous, to fade over hours. And I can program the ramp up & ramp down different from each other as well. Plus separate fade rates based on anything I want = time of day, triggers, events, etc...
It is endless the possibilities of fate rates available and how to use them.

It will be fine. We only have 18 years or so of examples to base this on. :)

In IL, Lutron RadioRa and Homeworks RF dimmers have had to go into metallic boxes all the time. The range is lower than when in Carlon boxes, but it's still acceptable.

Caseta now allows the first lamp dimmer commissioned into a system to serve as a repeater. Put one near where the enclosure will be located.

Yup.

In my case the caseta bridge is on top of the rack not 5 feet from where the panel will be.

Again I would never offer this as a solution for a client but for my own house, being poor and all it will be fine! If circumstances were different and I wasn't dirt poor from the wedding of HER dreams I would do panelized lighting all day long. But she's moving in in 3 weeks and she (rightfully so) can't and shouldn't have to live with a few lamps.
