If you are in the market for an E63 you should post in the AMG W213 section. The facelift definitely has an improved chassis and driving dynamics over the pre-facelift. That's what would sway my decision. Same reason I went for the FL C63 vs the PFL C63. The FL drives better. Technology definitely mattered for me as well, but mainly because the old old COMAND system is quite outdated now. However, the NTG 5.5 system and specifically for the 2019+ models isn't much behind MBUX. Both use the new Mercedes me connect platform and app so they get OTA updates, mainly for the maps so far. MBUX has nothing over the 2019+ NTG 5.5 in this regard. I've had MBUX in a few loaners, and frankly I'm not that big of a fan. The UI is optimized for touch and to this day I find touchscreens a bad idea in cars unless you are stationary. So while moving, the UI is awkward to navigate using the physical controls. Touch is essentially futile in an AMG while moving. Your finger will bounce around and it'll feel like target practice. I much prefer NTG 5.5 in that regard. With COMAND you also still get the jog wheel in the center console. I never use the touchpad in the center console and with the facelift that's all you have. I do use the touch controls on the steering wheel a lot, but with MBUX it requires a lot of swiping and you have to swipe in the right direction to get to the control that you wanna click on. It really is not very good to navigate if you don't want to use the touchscreen. Another thing about MBUX is that AA/CarPlay are not full screen. MBUX also seems to be a lot more buggy. It has IMO been rushed out the door. Hopefully they fixed most of the issues for the W213 FL, but you don't know until you've lived with it. The AI based voice control system is certainly cool, but for what I do use voice control, the system in COMAND works equally well and it gets periodic updates together with the map updates.
