- The kernel driver is i915 and it is used every time.
- The user space (xorg) driver hs 2 possibilities:
1. "intel" for xserver-xorg-video-intel. This is intel's native driver. It may not have a "stable" release they do package from recent git versions for it.
2. "modesetting" for xserver-xorg-video-modesetting. This is a generic driver that uses glamor for acceleration. BTW glamor relies on the Xorg code for acceleration and in Stable you have old Xorg and old glamor so modesetting support is less than stellar.
And at least in my experience on 2nd, 3rd, 4th and 6th gen Intel IGPs the "intel" driver is way better - you have the "tearfree" option (modesetting does not). Also basic desktop experience is better on intel.

User config is needed now to get the kernels to boot the video drivers properly. In my experience, I either get a black screen(no extra config) or do not have full aspect ratio(modesetting disabled). The xorg intel driver is at its last version in the Debian repos and has been for some time.

Though i believe you are wrong about it - ie xorg auto configures itself (this feature i think is some 10 years old btw) and uses the installed drivers automatically but it still uses user space drivers. For troubleshooting you would need to consult the xorg log file /var/log/Xorg.0.log.
As for driver versions on any remotely new hardware you need new kernel/libdrm/mesa/xorg drivers from backports (and if you happen to have something that uses glamor as backend, new xorg from sources).

The package page for the xorg intel driver recommends that you try to remove the driver as it is not needed anymore.
That driver hasn't been updated in 2 years also:
