With BlHeli suite you are sure that the esc have exactly the same input range and you know what is the range setted .
What it is really important with multirotors esc is that all esc have exactly the same range , the fact that esc range match transmitter range is not so important if they are not very different.
But try to set one esc with a 10% lower top range than others and you will see what happens then.
I prefer to do BlHeli suite esc calibration and skip totally transmitter Esc calibration .
I just check throttle range with Mission Planner and use the values in BlHeli suite esc ranges.
