I have been using Audacity 3 for making music with samples for a few years. And it sort of worked, but there were a lot of things that were inconvenient, like the project sometimes not saving, or getting a "clicking" noise across clips that I had to remove by manually fading in/out each end of the clip.
I tried the Audacity 4 beta a while ago, and it seemed super clean and like it fixed a lot of stuff. I am pretty concerned about the encroaching audio.com things (even though they are completely optional), but I still think this Audacity version has promise. I especially like how you can drag clips to time-stretch them.

Are you sure this isn't just the typical "clip/crop a sample at the wrong moment, in the middle of a soundwave, and you'll get a pop/click"? This problem happens all across DAWs and hardware samplers and such, usually there is a way to "align to zero-crossings" when you wanna avoid it, or called something similar. I'd be surprised if Audacity didn't have that optionally since before, or that they didn't have it before but now with Audacity 4 it would suddenly be used automatically, that'd be somewhat strange too.
