The Razer Blade stealth looked okey, looked like good quality build?
Still chiclet keyboard and unnecessary few ports.
I didn't go with X1 because I do occasionally need discrete graphics, it works with Razer Core out of the box as well (on linux, but probably X1 would too), no proprietary charger (it's USB-C), and I don't like Lenovo's trackpad - neither the feeling of it nor the two (for myself) unnecessary physical buttons and a trackpoint. I understand there's a cult following for that however, so to each their own I guess.
