The 2x2 matrix is a favourite layout for differentiating yourself from others. 'We, the good guys, are in the top right corner".
But people sometime force the framework somewhat. If you are having trouble filling the bottom left box, consider using a Venn diagram (a "best of both worlds concept").
If it is going to be a 2x2 matrix and your axis choice is a bit tricky, write things out in full. Rather than "ease of deployment, low, high" consider ignoring the axis name and write the 2 categories: "Big system integration project", "Up and running in 5 minutes". You can also write explicitly in the 4 boxes what they are about (BCG did that with their brand matrix: "dogs, cows, stars, question marks")
Framework in pitch presentation are different from those in a micro economics Phd thesis.
P.S. Presentation software SlideMagic's grid structure makes it really easy to make 2x2 charts (or 3x3, 4x4).
