Common specs comparison

As the PB-580T and the PB-770T are both Echo blowers, they benefit from the same level of quality and attention to detail. 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.

The Echo PB-770T, providing a CFM of 756, outmatches the 510 CFM of the Echo PB-580T. Your leaf blowing experience will therefore be outstandingly improved with the Echo PB-770T, as it should be able to move considerably more leaves per minute.
The Echo PB-770T with an MPH of 234 slightly exceeds the 215 MPH of the Echo PB-580T. 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 weight of the Echo PB-770T, which is 24.3 lbs, slightly exceeds the 22.6 lbs of the Echo PB-580T, and will therefore require you to carry around slightly more weight.
The Echo PB-770T's noise rating of 74 dB exceeds the 70 dB of the Echo PB-580T. Therefore, the Echo PB-580T will be easier on your (and your neighbor's) ears.

The Echo PB-770T has a slightly larger fuel tank, with the volume of 68.3 fl.oz., compared to the 62 fl.oz. of the Echo PB-580T. Thus, it can store more fuel and you may theoretically operate it for slightly longer, if their engines had the same fuel requirements.
In comparison, the Echo PB-580T's engine displacement of 58.2cc is slightly outperformed by the 63.3cc of the Echo PB-770T. This suggests that the latter consumes slightly larger amounts of fuel per stroke and will provide you with slightly more power.
Each of these leaf blowers features a 2-cycle engine. Thus, they both require you to have an oil/fuel mix to operate.
