Obviously if you're working on something truly hard real-time you probably wouldn't be reaching for these tools to begin with, but for the average embedded project it seems you will enjoy quite good latency and jitter characteristics by default.
I've read this, and frankly its comparing apples to oranges. These are not the same things though naively they may appear the same.
