I've used Toodledo for over 10 years and it has been one of the best productivity and task-tracking systems that I've ever tried. Its webpage is easy to navigate and works well, but even more importantly the app is seamlessly integrated and works perfectly. I use it for both business and personal tasks and have used it every day of my adult professional life. I have the plus plan and the customer support team is responsive to direct inquires/tickets.

I'm always looking for tools that show a lot of information, making it easy to scan. Too many tools nowadays seem built for phones and tablets only, with a TON of white space - which on a desktop, is all wasted space. On Toodledo I can see a lot more tasks or lists than on many other tools, because the views are compact. Love it!

It has a very flexible and robust set of folders, contexts, and even tags. Allows you to manage the different type of tasks across different projects. The recurring feature is also highly flexible allowing me to choose certain weekdays and even specific days of the week, or even after an arbitrary number of days. It may not have the most modern interface, but it is rock solid. If one cares about getting things done then this is the app to use.
