Common specs comparison

As the Echo PB-770T and the Stihl BR 600 do not share the same manufacturer, their overall build and technology in use can vary. Both products have their throttle located on the tube of the blower, which allows you to keep your left hand free.
These two products are constructed as backpack blowers, allowing you to comfortably carry their powerful engines and massive fuel tanks.
Both products are gas-powered blowers - gas is a reliable power source which you can refill in a matter of seconds.

In comparison, the Echo PB-770T, with a CFM of 756, beats the 677 CFM of the Stihl BR 600, making it the superior landscaping tool of the two, when it comes to the amount of leaves that can be blown per minute.
The Stihl BR 600 with an MPH of 238 slightly exceeds the 234 MPH of the Echo PB-770T. Thus, in comparison, the former expels air at a slightly higher speed, and should do a better job at blowing leaves on grass or lifting wet leaves and debris (acorns, etc.).

The heavier Echo PB-770T, standing at 24.3 lbs, dwarfs the 21.6 lbs of the Stihl BR 600, and may cause you more trouble physically when operating.
The noise rating of the Stihl BR 600, which is 75 dB, slightly exceeds the 74 dB of the Echo PB-770T. Even if this difference could seem unsignificant, the former is still slightly more noisy.

The Echo PB-770T's 68.3 fl.oz. fuel tank outmatches the Stihl BR 600's 47.3 fl.oz. You may fill it up with way more fuel and presumably run it longer, if both engines had the same fuel consumption.
In comparison, the Echo PB-770T's engine displacement of 63.3 cc is slightly outperformed by the 64.8 cc of the Stihl BR 600. This suggests that the latter consumes slightly larger amounts of fuel per stroke and will provide you with slightly more power.
Each of these blowers requires a fuel/oil mix to operate, as the Echo PB-770T features a 2-cycle engine, and the Stihl BR 600 is powered by the Stihl 4-Mix 4-stroke engine.
