Just to add a push to your decision, I used TechTool Pro for cloning for many years, and before that DataBackup X (really liked the latter, but they didn't keep up). I recently switched to CCC and really like it. Clean, comparably fast. Worth a try.
On a Mac since 1984.
Currently: 24" M1 iMac, M2 Pro Mac mini with 27" BenQ monitor, M2 Macbook Air, MacOS 14.x; iPhones, iPods (yes, still) and iPads.
