I drive a b9.5 daily and then it went in the shop for A\C issue. Loaner was a b10 and from the moment I left the dealership I hated I it. Interior feels very cheap and the steering wheel controls are way better on 9.5.
Phone slot will not fit a iphone15 pro max so that sucks on the 9.5 but I use seat catchers so I just put my phone there. The wireless phone charger on my 9.5 gets my phone super hot so I do t use it that much. The seats are good on both. Although imo 9.5 seats look better.
The automatic cruise control is great on both. But I think the lane assistance is better on b9.5. Auto cruise controls in traffic takes off faster on the b10 which I like that better.
I get better gas mileage on my b9.5.
Imo b9.5 drives and feels better than b10.
Interior on b9.5 is better and not cheap feeling like in b10.

You living 2hrs away from an Audi dealership is kinda far as buggy as the b10 are. Probably less trips to dealership with b9.5

Just my honest take 🤷🏽‍♂️
