I think at this point the brand reputation and software quality are a big selling point.

If you're trying to build a couple of units of some embedded thing where you need to toggle some GPIOs or serial devices in response to requests over the network, but don't have the expertise or resources to do it with a microcontroller, a Pi is a great option - you know you'll have software support, and you know that the vendor will be making the exact thing you bought for 5-10y.

For hobbyist stuff at home, I agree, though. A mini PC is probably better for homelab stuff, and an RP2350 or ESP32 is probably better for anything embedded or battery powered that you want to do.

Development speed is also one of the forgotten axes. I mentioned upthread a system I built that was done in less than a day. There's no microcontroller solution I know of that would have let me deliver it that fast.
