You can't go wrong with anything from the Thinkpad T or X lines (you might be able to find them refurbished/used for pretty reasonable price). The Dell XPS 13 is another decent option but can be pricy.

For my personal use i've been using the Huawei Matebook X pro since last year. Things i dislike: no linux driver for the fingerprint scanner, there wasn't an option for me to buy the model with 16GB ram without Nvidia (its not a problem if you plan to run Ubuntu, etc). Things i like about it: The screen (3:2 screen is growing on me), the built quality seems really nice, its light but feels very sturdy. Good port selection, It has two USB-C + 1 regular USB-A port. The battery life is really good.
