CD's or Vinyl?

Neither.  Streaming is better and more convenient.  

OK, you have a gun to my head.  CD due to the clarity and lack of background noise, as well as convenience. But there is always a caveat that makes such a a

generalization inaccurate.  Excluded are many digital masters in the 80’s to 90’s.  Masters from this time need to be chosen carefully.  Many had so much digital glare they were fatiguing, if not outright annoying.  With this subset, the original vinyl was better. 

I’m CD’s all the way. I sold my TT and records decades ago. While I have occasionally been tempted to go back to vinyl, it would just cost way too much. I don’t have even one record. 
And I have added a streamer to my 2,000 CD’s a couple months ago, I have access to plenty of music choices. 

Gun to my head = CD BUT, I'll take Streaming any day of the week & twice on Sunday as my primary source when there are no guns involved..

I would not dream of going back to vinyl. It is not an easy choice. But I have hundreds of CD's. Over the years most of my L.P.s have been stolen from me. 

SACD's are simply the best. P.S. I have got even with some.

As much as I enjoy vinyl, I would have to go with CD's.

For me, the sound quality is on par, or better, than vinyl. And I own fairly high end vinyl and digital playback systems. 

But my main reason may be, I am in the constant search and discovery of new: music, bands, composers, musicians, etc, and the vast majority of what I listen to* is only released on CD.

So, since the discovery of new music is more important to me, than any specific format, CD is my format of choice. 

*Prog, jazz, contemporary classical.
