offer a faster Wi-Fi signal
You're comparing theoretical differences but theories don't apply in the real-world (home) unless you live within an optimal, pristine, laboratory-type of environment.
Theoretically, I should be able to hit cruise control and glide down I-66 at 55 MPH; however, environmental conditions would apply: traffic, weather, debris, etc. It's the same for WiFi at home: congestion, contention, interference, walls, furniture, etc.
I think the key takeaway in your question is the Panoramic. I would follow widermouthopen's advice and buy your own gear. If you consider a few things, Mouth may have a recommendation.
- Roughly, how much area does your WiFi need to cover?
- One router or a mesh system (2+ routers)?
- How many users in your house?
- What NIC in your current devices?
- What NIC in your anticipated devices?
- USB ports to share a printer or storage drive?
- Parental controls?
- Lastly, how much do you want to spend?
