I think mine is a 9570.
Agreed on the switchable graphics issue. I think mine was compounded by a nouveau issue with this particular nvidia part. One fix I'd have been happy with would've been to have intel graphics always on. That matches what I do better anyway. But I could not find a stable way to do that.
I found that installing the nvidia proprietary driver and switching to intel mode kept it happily locked to intel, then there is a fix for intel graphics for Xorg (conf change) to stop tearing in videos like YouTube. Performance for things that use GPU rendering (like certain IDEs :() wasn't great so I switched back on Nvidia.
We are all in various states of Nvidia/Intel proprietary/nouveau drivers/modes here depending on personal preference but none of us have any real day to day issues (On Ubuntu 18.04 at least, which is our preferred distro).

I'll have to give that a try. Fedora's the (very slightly) preferred option here mostly because we're usually deploying to red hat stuff. But that is not a religion and would take a back seat to a working laptop. If the XPS15 worked at native resolution with good wireless, it'd be much nicer than my current linux machine.
A bunch of the Ops guys here run Fedora, I've heard it runs better than Ubuntu, particularly Gnome, but in the dev team we're debian so I've not tried running Fedora.
You also have to switch RAID to AHCI out of the box (if it came with Windows) but it's otherwise been smooth sailing from there.
As for graphics, Prime/Primus/Optimus (which ever it is, I'm never sure) is an issue with all machines and not a DELL issue, Linux support, in my experience, for switchable graphics is just terrible.
The machine I'm on now (XPS 15 9560) has nvidia always on, I used it plugged in 99% of the time anyway, I'm running Ubuntu 18.04 for work.
