But as with GNS3, you do have to source your own IOS images. Seeing that both the OCG and FLG don't come with full configs for their examples/labs, you do learn a lot trying to generate the config yourself based on a topology, some lines of code and show commands (and reading the authors mind for things not written down).

Hard to say, I think its really a mater of what you are used to, but UNL has improved greatly since reaching v1.0.x, and I can't see myself going back to GNS3 in a hurry. I did have a look at a GNS3 v1.x, but found it rather convoluted with the need for a VM for IOL/vIOS. The main pros would be its multi-platform capability... a wealth of Cisco support, dynamips, Nexus, ASR, ASA, vIOS, ACS, IOL, etc, along with F5, Fortinet, Juniper, Palo Alto, vPC and many more. Do a search on "UNL vs GNS3", there are a few comparisons out there. The licensing restrictions are still there for all platforms, regardless of vendor. Just as GNS3 requires a legal copy of IOS, IOL still needs a key. Still, people find what they need, its just a matter of looking.:) And remember, health competition spurs development, so we all win in the end!
