I bought mixbus way back at v1 or 2 before settling on Reaper. At that time, mixbus workflow felt clunky.

While I continue to love Reaper, I will always be intrigued by mixbus because the built-in mixer imparted a mix-ready tone before plugins. I've not experienced this in other DAWs (I realize that is a design choice and not a shortcoming of other DAWs-but it differentiates mixbus in the market). I'm going to give the demo a whirl!
