Viable is a broad term.

I use a single provider and multiple indexers, and it is an objectively better experience when compared to torrents. Very fast downloads and I almost always find what I am looking for. For old or esoteric stuff, I rely on Internet Archive or YouTube.

I do hit an infrequent failed attempt but that is due to me relying on a single provider/backbone.

Long and short, usenet is viable and convenient for me than torrents and paid streaming and gaming subscriptions.
