I'm currently using LG Gram 17 2021 model, 16GB 512GB config which I got for 89k and am quite happy with it using Linux.
Some things to note:
1. By default there's a black tape covering most of intake. This is intended to direct airflow from VRM to the CPU, but the path is too long causing overheating. I removed the tape and the laptop runs extremely cool now but has a fan whine noise. I'm fine with it but many might not be. Also not many people are comfortable opening and tinkering with their new laptop, so that's possibly a deal breaker.
2. RAM is limited to 16GB soldered. I can't seem to find a 32GB version of it in India. I'm usually just on edge of filling it, so could be a potential deal breaker for some. 2022 model is supposed to have 32GB models more readily available.
3. It has two SSD slots so I dual boot Windows and Linux in separate SSDs. Makes life a breeze.
4. The screen is amazing. 1440p, color accurate, 17 inches, 16:10. 400 nits. Can't ask for anything better. Only problem is glossy screen, something they fixed in next year model.
5. Battery life is okay. It's significantly better in Linux than Windows, but for anything resource intensive, you're looking at 5-7 hours. For normal usage, I've seen it going to 10 hours, but don't expect anything more.
6. Has 2 x Thunderbolt 3 ports with USB PD. I just connect to my monitor with KB and mouse connected, so just a single cable gets an entire setup going for me. Getting proper 4k 60Hz with HDR with USB connections on just a single port. Also 65W charging of course. It's perfect.
7. Build: Great lightweight, surprisingly sturdy, fully black minimal design. Lighter than my previous 13 inch Macbook Pro so that's something for a 17 inch device.
8. Keyboard is awkward. Touchpad is more towards the right side of the keyboard, so typing can get tricky in the beginning, but you get used to it. Not perfect, but otherwise, the touchpad and keyboard are good. The touchpad is an obvious step down from my Macbook, but it's as good or better than most Windows laptops.

Experience with Linux:
Currently running Fedora with KDE. Had some issues with sound, but I installed drivers manually and got it working. Other than fingerprint scanner, everything works including function keys, so I have nothing to complain.

It's certainly not perfect and has some quirks, but it's currently my primary workstation and I really like it. You can consider the next gen model as that has 12th gen processor which is way better, has anti glare screen and has a top tier 32GB model as well. But it's bound to be super pricey, so your mileage may vary.
It's one of a kind device. You can't find many 17 inch laptops weighing only 1.3 kgs while having a fantastic 1440p 16:10 display with extra SSD slot. Almost perfect for Linux if you're fine with opening it up and tweaking the thermal setup a bit.
