Likewise, I subscribe to both (and to Spotify family, used by the Wife). Tidal often has Pop&Rock that doesn’t always appear on Qobuz. The overall cost of subscriptions isn’t more than the price of a couple of CDs a month, so I find them quite reasonable.
Subjectively, I find the sonic quality of streams via Qobuz to be distinctly better than the exact same album on Tidal. I have no idea why and I haven’t really dug into it.
So, another vote for Qobuz if you have to chose.
