wouldn't take your car to either of them unless you want to be ripped off for items you do not need.
disc's and pads for 6-700 quid! all they do is up sell, and con you into parts that are not worn out.
Whilst I agree that I wouldn't entrust a new EV to any generic retail chain for servicing, I did have need of Kwik-Fit a few weeks ago due to a flat tyre on my wife's car on a Sunday morning (and they were the only place open that had the right tyre).
The service was the best I've ever had from a tyre shop.
They spent a long time inspecting the tyre to try to find the puncture (it was a really thin piece of wire in the tread), repaired it, and then sorted the refund of the online pre-payment. They didn't even charge for the puncture repair as my wife is a doctor. (free puncture repairs for NHS staff).
sorry this is a bit off-topic, but sometimes they don't deserve the poor reputation they have.
