Do battlecards still exist lol?
So wireless from Meraki or Cisco or Ruckus or Aruba or XYZ is going to be for the most part, give or take some percentages, roughly the same. Model and chipset and performance will vary of course. However at the end of the day they all essentially do the same thing, 802.11
Assuming all things equal, the question is which vendor has the best 'solution'. Meraki is notorious for making things easy (sometimes too easy for us engineers who like knobs). Meraki dashboard is a breeze and AutoVPN (not wireless related, but you get my point) was a blessing for engineers.
Cisco has a knack for making things difficult sometimes. I've dabbled with Aruba once or twice, they are pretty good too.
Do you want your control-plane to be cloud based or local? All these types of architecture questions will pop up as you go down the line.
This link here I found a few years ago and while it isn't perfect and I might disagree on a few things, its pretty awesome and if you read through this you'll have better insight into what decision you want to make:
