If you are used to working with smaller projects, such as a putting together a customer deliverable or prepping for an event, Basecamp will serve you well. The writeboard and messaging features are useful for distributed workers, and having everything in one project-oriented micro-site lends a lot of efficiency to this tool.

But if you are doing any kind of serious project management, and need to track tasks more closely, Basecamp might not be the best tool for your organization. Price should be a consideration, too: there is no free option, so the base of the $20 per month plan lets you manage 10 projects with 3 GB of storage. The highest plan at $150 per month enables unlimited projects and 100 GB of file storage. (All plans have unlimited users.)

This is a more streamlined plan than AceProject (who wants to count tasks?) and Basecamp gives you more storage space overall, so in that, it's not a bad deal. But you will really need to know what you want in a project management tool before signing on.
