Which broker's data feed is better?

[lfbxindekaishi]

I am a user from China. It is my first time to use NT8.
Question 1: Which broker's data feed is better? Is it enough to connect to the broker account using NT8? Or do you need to do something else to get the data better?
Question 2: Are there any other costs after purchasing the LIFETIME version of NT8?
Question 3: If I want to use order flow-related functions, do I need to purchase additional plug-ins?
