I think they have mostly equal features, but I don't use Dropbox extensively so I can't say exactly. I actually am a nonpaying user for Box as well.

I have the ability to edit/create documents in Microsoft Office or Google Drive formats right in my Box account. I don't use any killer apps though. But it works well enough for nearly every use case I've had in the time I've used it, with the exception that file upload size limit is small. Might be around 100 megabytes max.

There's also versioning for files, if you need that kind of feature.
