It's an interesting choice (and I like that series a lot) but I feel like they would lose on account of having negligible offensive capabilities compared to a lot of the alternatives. Though I suppose those silver bug aliens would perform better in that regard but as impressive as tearing a planet to pieces for spare parts is, their method of doing so is very slow and inefficent compared to something like the Death Star.
