I've done 800 miles now in the new work car, the Nissan Ariya.
Good things and typically Nissan bad things. Although my paperwork says I have the 63kwh battery it's actually the 87kwh which is nice

Not going to mention that as Mr Inland Revenue will tax me more (sshhh).
I'm getting ~330 miles range and that makes my working day easier as I can get where I need to and back again without stopping to charge (I still stop for lunch but...)
It came as standard with a heat pump, very good efficient heater, which is important because there's no heated seats or steering wheel. Only time will tell if this is a problem in deepest winter.
The onscreen menus take a bit of getting used to, there doesn't seem to be any defined method to their madness in where they put things. Some important setting are accessed via the left screen, others via buttons on the steering wheel. Some haptic controls, others that look haptic but are actually clicky buttons.
It will charge at 130kwh on DC and 20kwh on AC. Charge time - 17% to 100% took 12.5 hours on my 6.8kwh home charger which is a long time but I am getting home with around 40% charge left so it fills up faster than that.
It's huge! inside especially and pretty big looking on the outside too, the drivers position doesn't feel cramped at all and the high driving position is a joy after the MG5. No electric seats though which is not an issue for me as I'm the only one driving it but it might be for others.
I use a 12v inverter to charge/power the laptop but the car doesn't output enough power to charge it while I'm using it, the MG did that no bother. The laptop charges fine on the road but runs down quickly in use so I've taken to bringing my small Anker power station as a back up.
All in all, I'm happy driving it, it's a nice car to drive for the most part once you have (every trip) shut off all the nanny nagging beeps. A big step up in quality from the MG and so much easier to get into.
Would I buy one? no chance, the small battery version is £45k new and if I paid that much I'd be very disappointed in what I got for my money, not withstanding the good bits.
