I have very limited experience with Consul and Vault. I do know that the older versions of these services, when they were CLI, were very unpleasant, especially the Vault. Consul didn't immediately meet our needs since it has no form of an audit trail, so the purposes I'd hoped to use it for weren't really fulfilled. I did like what the service seemed to provide and how it provided it. Just be warned that the lack of audit trail can be a problem if you want to use it for feature flags, etc. It will still need to be backed by some sort of store, like git.
