Those are enthusiast boards targeted at enthusiasts.

They got some nice features that most people won't actually use.

But if you got a custom ek loop and studio grade headphones and want to OC as much as possible, then it's a decent buy.

Personally I have a hard time justifying a Z270 board with a pricetag over 200$
All of the Big 3 (MSI, Asus, Gigabyte) have assorted 'flagship'/gaming/ROG/Tuff, Fatal1ty, / whatever monikers to attach to some of their models, but, typically the basics are the same...

Me personally, it'd a hard sell to get me to ever buy some of the Z270 variants that come with two or three extra features (attached audio amp, wireless, fancy shrouds styled to look like heatsinks, etc), but at sometimes up to a *$200-$250 premium* over a basic model such as Asus Prime Or MSI Z270A SLI PLus, etc...? Good luck with that. :)

Some folks need/want those features however, God bless them; I guess someone is buying them, or they'd be out of production...

Not true about the premium audio, i had 2 boards with premium audio, the hero VI and asus prime x370 pro (which i still have now) both of them are "audiophill grade", it is true that the audio quality is much better compared with the past but no matter what my asus xonar u7 blows them away in clarity and sound balance (the xonar covers much better the high frequency and the mids, the bass on xonar is almost the same maybe a bit more clear on xonar but it is not much diiference). No matter what i tried, i could not obtain clear and crisp highs on the motherboard audio soundcard.
 
Quality is overall good of course.
But a 160$ board already comes with great quality.
You might see an advantage hunting for 5.2GHz and taxing the system won't put the board under so much stress. It can compensate heat better and so on.
The question is if you'll be taxing your system enough for the benefits to kick in as a 160$ board is anything but bad. I advise against the lowest end 100$ boards, but something between 140-200$ comes with decent quality already.
