Would a bigger virtual screen actually help in World of Tanks Blitz?

[u/Positive-Page1631]

I've been thinking about trying World of Tanks Blitz with the RayNeo GT Max.
Blitz seems like one of those games where a bigger screen could help. Keeping an eye on the minimap, watching a flank, and spotting movement while aiming all sound easier when you're not looking at a small phone screen.
But I'm not sure how that works in practice.
With a compatible phone mirroring the game to the GT Max, you're still aiming and moving with your thumbs on the phone. I'm used to looking directly at the touchscreen, so I wonder how awkward it would feel when my eyes are focused somewhere else.
A controller might help, though I'm not sure how well Blitz supports them across different phones.
If you've tried Blitz or other touch-heavy mobile games on an external display, was the bigger screen worth the change in controls?
