I like syncro for its ease of use and simplicity. For our systems, it's integrated quite well with RMM, scripting and other remote features. It's generally quite stable and I believe my directors are happy with the pricing considering they have been using it for quite some time. Training was relatively simple when I first started but I feel as though the smart search system needs some refining.
I use Syncro for managing clients as an MSP, and it allows me to easily funnel tickets into a legible and easily handled format. I also enjoy the remote deployment options available for business clients. The dark mode is truly dark mode with no flashes, which is usable for long periods without eye strain and helps with my workflow.
