I wouldn't recommend BATC at all. It's not ready and still full of bugs to basic ATC functions.
IE: I flew into KALS tonight in a CJ4. I setup an ILS approach and instead the ATC wanted to vector me for manual approach to a DIRT RUNWAY. And when I asked to change it, it gave me the same bug it does everytime which is a basic runaround which results in being given the runway change and then having the ATC revert back to the old one.
And this isn't a one-off situation, it's done this OVER and OVER again to me. I don't fly large airliners, and I don't often fly into large airports. I suspect nobody is really testing this beyond those, because every airport I fly to winds up with this situation.
I finally asked for, and to their credit, received a full refund tonight. I might check back later to see if it's any better, but then they banned me from their discord, which seems petty. I'll take my biz elsewhere at this point.
