Kernel less, event driven- components based architecture allowing direct hardware manipulation. Extremely small footprint and low system overhead. Very ideal platform for power-constrained applications. Single stack for both function calls and interrupts. Strong libraries supporting every possible protocol required for wireless sensor networks.

I am not sure about current support of TinyOS. But when I worked on TinyOS back in 2014 for my sensor network application, TinyOS was pretty new and I found a high learning curve considering lack of online support or tutorials. Initially, I found difficulty installing and configuring TinyOS environment on my primary OS (i.e. Linux). So, I consider the initial high learning curve to understand the TinyOS architecture and its libraries, very crucial part to continue the journey of sensor networks application design.
