I don't know much about them (such as detailed differences in features and functionality), as we never compete directly due to using totally different approaches.
Basically, DoubleTake is legacy solution that is designed for physical servers, and as such it require data processing agent in each VM. This approach does not work well with virtualization due to resource consumption overhead from the agent and other issues.
Veeam, on the other hand, is designed specifically for virtualization, and performs agentless processing. We can get data directly from the storage, instead of pulling it through VM and production VM network.
Hope this helps!

But for grins this is my favorite part of their post "While we’d love to continue that pricing going forward, as of the end of this month (July, 31 2012) we will be returning the Double-Take Availability Virtual Edition pricing to its normal $1095 USD per VM Guest level."
Key differences aside from cost and RPO are multiple replication points allowed with Veeam...none with DT so if your machine is corrupted on source then it is corrupted on target in a split second and Veeam gives you true failback and testing capability where DT is really just meant for failover. They do advertise the ability to fail back but there are several caveats to this and it is a multi-step process.
Hope this helps...the key thing to keep in mind is that with Veeam you get a true DR solution...not just backup and not just replication.
