Got to try the new Pinion MGU today.
I'm sorry to say it did not live up to expectations. It was too noisy from gear 1-7 (or 8?), the gears were IMO a little too far apart and the gear changes unrefined. It also died on me 2 times during a 15 min test, which required a restart of the system. Unless there are some serious refinements which can be had through a firmware upgrade I would not have this system on a trail bike, even if I could stand the noise. Power was good but maybe not great.
I jumped straight onto a Riese & Muller ebike with Bosch motor + the newest electronic Rohloff gearing. This felt a lot better. Quieter, less gap between changes, better shift quality and probably also somewhat more powerful. Would be a good combo for a trail bike if you value low maintenance over the added unsprung mass. Perfect for a hardtail commuter bike.
In summary the Pinion MGU felt like a 1st gen product, hope they can improve on it over time.
