I just bought the q326fa.
Pros over lenovo:
Nicer bezels, face recognition (if you like that), back lit keyboard, better specs, I prefer Asus keyboard. Also comes with the adapter for hdmi usba, lighter (weight) and more compact.
Pros for lenovo over asus:
Docking station for the stylus, thunderbolt 3 usb c ports, and it claims hd webcam... bigger screen,
My experience with Asus:
$899.99 last week during the sale Making my decision for me and I love Asus laptops and their keyboards
The laptop has a more glossy display but I think the colors and picture are fantastic.
Webcam is ehhhh, kind of laggy, the ir face recognition works quite well, snappy and the touch screen works well, touchpad works well for me, but you can adjust it. I had to update a couple drivers after the Windows 10 1809 update. Speakers sound fantastic, I haven't tested the Bluetooth yet. And there isn't too much bloatware from asus that you can't get rid of.
The fan is quiet in my opinion and only kicked in when doing all the updates after first turning on the laptop. Since it rarely comes on. Battery life was about 10 hours for me the first time. Now for this performance and thermals I was only browsing and watching videos.
I'm disappointed that my left hinge creaks like quiet candy wrapper at times and my keyboard "p" key is a little janky. The build materials are nice, but Dell beats them in my opinion. The Asus is little more style, less tanky. I know a buddy is selling the yoga930 or their older 2-1 I think and he doesn't like it. Personally I prefer Asus especially woth the price I got. Also I'd prefer xps 13 2-1 over the lenovo if you can get a discount and buy an external hd webcam.
Let me know if you have any other specific questions, hope this helps
