If I have the time to plan ahead, I much prefer to prepare with a full test suite that I fan rely on before considering a rewrite. Rewrites are difficult to estimate, difficult to pull off, and often demotivating as the work drags on. Having a suite of test coverage that I can reuse for the rewrite both gives me an easy check to make sure functionality isn't lost and a cheap bit of motivation as I see tests slowly turning green.
