Right feature set for many pdf tasks

I have three pdf applications: PDFPen Pro, Acrobat Pro, and PDF Signer. I use them for different things.

I like PDFPen for pdf markup, comments, and general pdf editing.

I am forced to use Acrobat for some federal documents that require Acrobat, because they have some proprietary features.

PDF Signer shines for the once or twice a day that I need to sign and date something, or a short form. Simple, quick, no settings to fiddle with. I use PDF Signer much more than the other two combined.
