Right. So what's the deal here? I've got a MacBook Air arriving on Monday, but I'll be annoyed if the screen is less bright than my current 2014 MacBook Air.
"At 286 nits, [the 2014 MacBook Pro] is dimmer than the XPS 13" -

New MacBook Air has 290 nits according to the Dave2D YouTube review mentioned above.
So either some info here is wrong or people are mistaken.
Regarding the nits, results seem to vary. Laptop Mag as you might know measures the 2018 Air's display brightness and gets 234 nits. Trusted Reviews does its own measurement and gets 305 nits.

Why the variance? Maybe different batches of 2018 MB Air's have different displays, some brighter than others? Or maybe the various tests aren't strictly comparable (e.g. one tester has auto brightness on and another has it off). Who knows? The best thing in my opinion is to live with the new Air for a week and try using it in different lighting conditions to see if it's bright enough for you. If it's not, take it back.
I bought a 2018 MB Air to replace my early 2015 retina MB Pro. I've used this Pro in many different lighting conditions over the past 3 years and never felt it wasn't bright enough.
In a side by side comparison, my 2018 Air's brightness is virtually the same as my Pro's brightness (not surprising since both are rated at 300 nits). Since my 2015 Pro's display has always been bright enough for me, I'm confident the Air will, too.
I also viewed a variety of video clips and high-res photos on both screens at the same time. I believe the 2018 Air's display is no worse or better than my Pro's display. (One difference: My Pro has a slightly cooler color temperature than the Air.)
I know the newer (2016-2018) MB Pros have better and brighter displays than the 2015 and earlier MB Pros, most especially the Touch Bar models with True Tone display.
I'm sure many people will choose the 2017 ntMBP over the 2018 MBA for its better display and processor, and I can't blame them.
For me, the 2018 MBA is plenty fast enough for the kind of work I do (a lot of writing, a lot of data analysis, some presentations), and I like the MBA form factor better than the MBP's (I have a late 2016 MBP with TB at work). So it's the right choice for me.
