Somehow your list misses Librem 5, which is more powerful than others, although not as powerful as the Nexphone will.

It is hard to associate in the same sentence the word "powerful" with a quadruple Cortex-A53 CPU.
Cortex-A78 is in a totally different class of "powerful", when compared with Cortex-A53. Cortex-A53 has not been designed as a top performer among Arm CPUs, but only as a low-power core. Even at its launch, in 2012, 14 years ago, Cortex-A53 was much slower than the older big Arm cores, like Cortex-A15 from 2010. I am aware of this from direct experience, because a decade ago I have developed software on several SBCs with Cortex-A53, including Raspberry Pi, and also on an ODROID model with Cortex-A15, which ran circles around them, and unlike them it delivered a passable desktop experience.
On the other hand, at its launch in 2020, Cortex-A78 was faster than any older Arm CPU cores. It was then surpassed by the Cortex-X1 launched simultaneously with it, and then by the Apple M1, launched later that year.
Even if some enthusiasts have used old Raspberry Pi and similar SBCs with Cortex-A53 as PCs, that was really not wise as they were too slow for a comfortable use and there were faster alternatives with a similar price (after you added the cost of all required peripherals).
It's more expensive and not sufficiently more powerful: I would also have to pay customs duties to import it into Serbia. The above are actual devices I own or have owned, it's natural I did not get all of them (including like PinePhone Pro).
