Isn't this a bit too harsh on them? We've had good experiences on T and L series.
I am using L470 with fedora 27 for the last 2 years and I have not had any issues so far. I have gone till 78 days without a shutdown. It's been more stable than windows on suspend to ram cycles.
I did have issues with fonts out of the box but fixing was easy. One of the advantages of using Linux is it forces you to fix the broken parts and personally it has been a very rewarding experience.
