Are Thule backpacks still good?

I bought a Thule Crossover eight years ago and the zip on it has finally gone. Short of getting a local seamstress to fit a new zip, I think it's time for a new one, and am a bit tempted by the Thule Crossover 2 30l. Are Thule still good? Is there anything else of the same sort of size that I should be considering?
