It can landing sync/cancel as well.
I may have actually properly remembered to save a replay of me doing it, to those who doubt... I'll have a look for it later and see if it passes the Radical Test.
It does alright damage, it can kill, it's a lot safer than you'd expect, especially if ledges or platforms are near by.
There's likely combo set ups into it that are of more benefit in a given scenario than tornado or perhaps shuttle loop even.
Although everyone and their mother would think "Nah mate, i'm just going to dash attack/grab in a tech situation instead", you can cover most options with it at once, bounce cancel on a misread, and if you are near the ledge and pull them with you slightly off stage and angle it in such a way that you grab the ledge afterwards, you have ledge drop nair/bair as a feasible set up. In general, using drill rush near the ledge as an edge guarder is under explored.
Also a lot better in doubles IMO; I'd say it's closer to brawl tornado in terms of doubles utility than S4 tornado.
I'm yet to do it, but I have
the dream of up airing someone above me, waiting/reading the air dodge, than drill rushing into them angled upwards for a stock. It will kill off the top stupidly early if you can drag people up there, it's just how are you ever going to be up there for it? Reason the idea came up originally was from a janky disadvantaged state mix up, which I guess could be worked on in itself and probably be reliable, but
THE DREAM.
