SpeedQueen and Miele tend to do no-nonsense designs with control panels. Miele's are a bit more sophisticated in terms of options, but they're relatively gimmick-free compared to some machines, especially some of the LGs and Samsungs which are more like a mobile phone than a washing machine.
The most important aspect of a washing machine is the design of the drum, the sturdiness of the build, the mechanical design of how it prevents the drum from vibrating too much i.e. shocks, springs etc and the power and reliability of the motor.
A front loader with a fairly mediocre size drum, but a powerful motor and excellent drum design will still produce far better results than a machine with a bigger drum, loads of fancy electronics if it has an inadequate motor and a badly designed paddle / drum system.
Remember, with a front loader your aim is to flush water through the clothes. They aren't tumble dryers and they don't necessarily need loads of room for clothes to tumble. What they need is an ability to slosh loads of water (not necessarily use lots of water) through the load using paddles and powerful rotation (i.e. lots of torque).
Also, when it comes to rinse performance, a front loader relies more on spin extraction than on sloshing around in water. You're aiming to wash - spin - re-saturate - spin - re-saturate - spin - fabric soften - final spin.
So, again that performance is dictated by mechanics, not electronics or drum size.
That's why I would say the SpeedQueen machines are quite likely to be excellent.
Same goes for Miele and a few others that are almost achieving commercial laundromat build quality scaled down for a household design.
