We have both, it works fine, and both platforms have their own goal.
I think the most important factor is archival work. Discord is transient, anything older than a day is lost, and as far as I know there's no public search history anywhere (gitter does have that iirc?).
There's a LOT of information and history in old forums and even old mailing list threads. I mean sure, 99% of it is probably useless, but it's that 1% that makes it worth keeping around IMO.
