I can't say one way or the other as I don't stream but there are plenty of reviewers out there who've expressed a preference for CDs over streaming. One reviewer finally found one streamer that bested his CD and stored files but it cost north of $15K just to be incrementally better. I could live without that, quite easily.
One thing overlooked is all the time, money, blood, sweat and tears it can take to assemble a fine streaming set up. Mastering that, how could anyone say it's not as good as playing a CD?
It's like some backyard garage mechanic who can keep his car in proper working order thinking he's a master mechanic. You always see their cars ending up on jack stands in their driveways.
All the best,
