Are 4G/3G Proxies really that much better?

I have heard about people using 10-20 accounts per proxy with 4G/3G proxies. Are they really that much better then other proxies? I know one reason is because they are of course mobile and most people use their mobile data apparently to use Instagram. But 20 accounts seems quite extreme… I am asking because I am for a long time considering to buy those types of proxies.

Also:

  • Do you really get less email verification, phone verification etc. with 4G/3G proxies ?
  • Ho much GB does do I need for 1 Instagram account? (Not all plans are unlimited in my price range)
  • 4G vs. 3G and why?
