…it’s all about feel with mixers IMO, good to know your way around Pioneers because of their ubiquitous presence in venues (assuming your ultimate aim here is to ‘play out’ of course!).
Honestly think that on the kind of soundsystems most people have access to, sound quality is much less of a significant issue these days, 95% of users are fully digital and new generation Pioneers seem to have eradicated a lot of the issues that the older mixers had.
For me there’s definitely a compromise in build quality though, even the Euphonia (AlphaTheta, I know!) feels a little shonky on that front, the main pots/ISO’s feel fairly solid, but the EQ’s/FX switches/knobs could literally be from any other Pio mixer/controller- not what I’d expect on a £3.5K bit of kit, and it’s actually a mixer that I quite like based on its features etc.
