It's time someone starts taking a look at such shady marketing practices. It's misleading, and borderline illegal to advertise such features that clearly do not work as advertised. Not sure if the guilty party here is the SoC manufacturer (BCM) or the various router manufacturers all pushing these bullet points in their marketing material.
I would agree here - it's marketing, and the capability is there on paper, however as RMerlin points out, most folks will likely never see the full capability of the devices as they're currently being marketed.
The best improvement I've seen on the recent crop of Wave 2 devices is
- 4SS and more Radios per NIC - The impact of the 4*4:4 configs, as all clients benefit from the additional radios and MIMO capabilities - even single stream devices benefit there, and two/three stream clients even more.
- MU-MIMO - not so much for MU, but the additional compute capacity, along with enhancement client management needed for MU (sounding/ranging, scheduling, and better beamforming) benefits SU clients as well as MU clients
- DFS/TPC enhancements - was good in Wave1, so far seems even better in Wave2 - this has knock-on benefits for all bands, esp when AP's are set to auto channel, as they are now more agile in channel selection and interference avoidance/mitigation/minimizing
- TurboQAM/NitroQAM - not so much for 2.4GHz (e.g. none), TurboQAM (QAM256) in 5GHz, that's part of the Spec - but QAM1024 is definitely non-standard, and difficult to actually see due to noise floors needed - same goes with TurboQAM in 2.4GHz, most areas it's just too noisy to use...
- Multiple WiFi NIC's on the same band class - e.g. SmartConnect/Tri-Band - just my opinion, but the downsides (intermod RF interference in the near field), I've never really been a big fan of that configuration, but that's me...
