I agree that the 3B+ was the best Pi but for other reasons:
The Pi 3B+ had the perfect balance between performance and price with the performance being good enough at the time.
Design flaws at launch. Remember the Pi4 CC1 & CC2? POE getting pulled from the market?
Pi5: 5V 5A USB-C??? There is now 45W USB-PD (@15V) that would be compatible with generic PSUs but they went proprietary with 5A@5V.
They put big customers first and let everybody else starve during the shortage. This forced me to alternatives and I have to say they work just as good and cost less.
Jacking up retail prices: Even Intel x86 is now cheaper than a Raspberry Pi.
