Toggl and Freshbooks here. I personally love Toggl - some of my favorite features are its "you've been idle" notification that lets you drop, keep, or move the idle time to a new entry, the extended entry autocompletion (autocompletes all fields from typing into the description), and how easy it is to continue. The cloud solution helps a lot - I have a setup where I can just hit super-shift-e to log out of Ubuntu and close all programs and simply walk away without losing anything.

My one issue with Toggl is that it only syncs a specific task with Freshbooks once. This can be a pain at times if you need to go back and change some previous entries. Overall, however, it works pretty well.

What have your issues with Toggl been?
