I think the Thinkpad E series might be considered cheap junk here, but my Ryzen 7 E14 with 40GB RAM runs Windows 11 and Ubuntu great.
I am using the extra SSD slot for Linux so I didn't have to partition anything. All the hardware works (though I haven't tried the fingerprint scanner yet). The only issue I've had is it doesn't love waking up the DisplayPort through the hub I bought, but that's likely a hub problem, and it actually works better in Linux than Windows.
I am quite happy with my core i7 Thinkpad E580 maxed out at 32GB of ram on Fedora. Keyboard is nice, battery life is decent, screen is mat and availability of spare parts and I am quite confident on the availability of spare parts and batteries in the future. Lots of space with the nvme + ssd drives.
I was super tempted by the E14 this year as they had one with 40GB ram and discrete graphics but the 200/300 NITs display turned me off. Ended up getting a P14s instead
