Qobuz vs idagio vs primaphonic


What is the best streaming service for classical music in terms of content, quality and reliability ? 
I have Aurender and node for streaming. Currently have tidal which works well but content seems lacking.

@OP,
The Aurender app only supports Qobuz and Tidal- at least it did when I owned my Aurender last year.

One data point: Primephonic has the entire Bonynge/LSO Rigoletto with Milnes, Pavarotti, and Sutherland, also the entire Serafin/ la Scala set. I didn’t check track for track, but it also looks like they have the entireLevine-Met recording. (Maybe that’s three data points.). So it would seem they have some opera.  I would be curious to know what holes people found in their opera stock.
Not to belabor the point, but Primephonic also seems to have many Walkure; in fact, scanning the app open beside me, it seems they have plenty of Rings.
