VNC Connect Home vs Home with Raspberry Pi

Hello there,

I'm bit confused what are the extras of hte Home Plan when used in conjunction with Raspberry Pi?

It is said that 

That links gets me to https://help.realvnc.com/hc/en-us/articles/360002249917-VNC-Connect-and-Raspberry-Pi. The only difference I can see is, that I'm able to make direct connection, which is usually not possible with the Home plan. 

It that correct?
Do I still miss something?

I'm still limited to 5 devices, if these are only Raspis? 
So if I buy a sixth one I either upgrade the plan or create a seperate account?

merci for some clarification 
Stefan
