What I see that makes me think the Breezer Liberty 1.3+ is a good value is:
* dynamo hub and lights
* Shimano hydraulic disk brakes
* rack, fenders, kickstand

Each of those bullets is arguably worth $100, or would cost $100+ if you had to buy it and add it on. If you are not interested in all those goodies, then Liberty 2.5 is MSRP $499.99

Looking at your original two options though, I see rack&fenders already (check), disk brakes, but not Shimano (half-check), and no dynamo. At the listed prices, those are also pretty dang good values. If you're not tempted by dynamo lighting, than probably better value than the Breezer.

Of those two I like the look of the Giant a little better, but like noglider, I prefer Jamis as a brand.
