Upgrading from EM160R_GL, what 5G M.2 Module should i upgrade to?

I am based in the UK and looking to upgrade from my Quectel EM160R_GL module.

Should i upgrade to 5G RM521F-GL or 5G RM520N/RM510Q-GL?
Between 5G RM520N and 5G RM510Q-GL, which is better? I’m assuming RM510Q-GL as it supports mmwave?

Current is the 520 521 and 530
520 sub 6 2x CA SA NR
521 sub 6 3x CA SA NR
530 has mmWave but I don’t know much about it.

I believe the rm521F-gl is the latest and greatest but I am not sure if production units are being sold right now or all currently available on places like AE are engineering samples which are not supported and not updatable.

I plan on buying from AE. How do you determine which are engineering samples?

530 seems to be better than 521 according to below

If it is not mentioned in the title we have to ask the seller.

Look at the theoretical max speeds. If you have mmWave available in your area then a 530 is probably a good idea. I always thought of the 530 as the 520 with mmWave capabilities. If you don’t have mmWave then you’d probably want the 521
