I like that you can connect to your Google Analytics account directly from within their dashboard so it makes tracking much easier! It's pretty easy for newbies as well since they don't need any additional software or plugins installed if doing simple tasks such transferring traffic between campaigns/accounts is what we do most often with this tool (which has been great!).
The only thing about clientflo i dislike sometimes when switching accounts are getting confused at times which email address goes where but not too big an issue because its very quick once figured out how everything works :) Great product worth checking into especially now given there price reductions over last year - best way forward in my opinion would be more training options available online etc rather than having people come through our offices every few months just incase anything changes during those appointments ;) Try them before buying otherwise may end up wasting money by going.
