I've been using a HP Spectre x360 (13") with Ubuntu 18.04 for the last couple of weeks and it's been working very well for me. I even use the tablet mode when reading PDFs.
Price wise it's quite cheap (same specs as the Dell: i7, 16GB, 1TB SSD, 4k screen) as you can usually find a coupon online. For me it was about EUR300 cheaper than the XPS currently is. So far everything has worked out of the box with exception of the fingerprint reader on the side.
