X-series is always a safe bet if you want something a bit more portable than the T-series, but with the same build quality. I don't know about the newest (x280), but I'm rocking the previous X270 and I'm really happy with it.

I also never see people mention it, but the L-series feels a bit underrated. I handled some older ones the other day and was super impressed by the build quality. I think they go for like half the price of T-s too.

L540s (4 or 5 years old now) used by the dozen in one of the places I teach, the managers have them as portable work machines. They seem reliable, they get a beating. Quite big 15inch screen, thick bezel &c.
