All these apps have their issues. I work with colorists daily, and am on Slack channels and other forums with folks running PrPro, Resolve, Avid, Baselight, FCPx, you name it. All have their lists of bugs and problems.
But on some systems, one app will perform much better than another. If what works on your system is X, well ... then that's probably the tool to use. In reality, they're all simply tools. Fancy hammers. Use the hammer what works for you.
Past that, as Sumeet noted, if you posted your troubles we other users might be able to get this project moving.
