Required : Mechanical Keyboard advice

I’m planning on buying a new mechanical keyboard. Budget at best can be 8K.

TL;DR - Read the considered keyboard list/Questions list and please drop your opinions on them.

Long version -

Why am I changing? - My existing mechanical keyboard - The Archer Tech Lab M200 has started having faulty key presses. I’m looking to upgrade to a better board now.

My requirements -

My must haves are wireless, Volume Knob and per key RGB.

Good to have would be Hotswap.

Nice to have would be QMK/VIA and openRGB support.

I have no clue about the different switch types, other than blue for click, red for silence and brown for thock.

I’ve used only a 100% keyboard to date and haven’t really considered a smaller size keyboard.

I do tend to use the Page Up/Down and Home/End keys quite a lot while typing.

I initially considered a 96% Keyboard but then felt it was too similar to the 100% and not much of a difference in footprint.

75% feels right, but I haven’t yet tried it physically. I do use the numpad quite frequently, but I felt it would be easier if I could use layers on a 75% keyboard instead of lugging around a full size keyboard.

What I’ve considered until now:

  1. Aula F99 Pro - Fits everything I want, but is 96%.
  2. Aula F75 - Fits everything I want,is 75%
  3. Roy Kludge R75 Wireless - Leaning most towards this at this point.

My questions:

  1. How do both these companies fair for a long term use case? (Say 5 years)
  2. 75 or 96%? Consider my usecase to have some numpad usage, but mostly just the letters, Pg Up/Down, Home/End and WASD/gaming.
  3. Is a 4000mah battery enough or is more required?
  4. The 75% keyboard is quite lighter compared to the 96% keyboard. My research shows heavier keyboards better. Is this true here also?
  5. What is the difference between the cream and beige switches on the wireless version of the Royal Kludge R75?
  6. Should I even be looking at non Chinese brands?

Thanks for all the help folks..!!

Cheers
