I actually switched from Thinkpads to a Legion 7 2021 and I'd recommend them over Thinkpads. It is by far the best Linux experience on a Laptop I've ever had.
* upgradable RAM
* two NVMe slots
* actually good keyboard (that unfortunately is part of the case, but replacement parts are available)
* the glass touchpad is better than my P14s with the X1C glass touchpad mod.
* the panel and refresh rate is very good and there's no lottery.
I don't know why Lenovo cuts corners on their business laptops, especially in the last two points.
It's heavy, but I don't lug it around too often, and having a 140W (max power spec) 3070 is great.
Just avoid placing them vertically on a stand, I had to replace the thermal assembly eventually.
