What I find interesting is that I prefer Metric. I grew up with both and am perhaps biased due to my Engineering background.
However, since most woodworking tools are Imperial (and this is continually propagated by the manufacturers due to the US market), I have found some comfort in adapting to thinking of everything in terms of ¼ and eighths and multiples thereof. It does not help with the materials though! Materials supplied are fairly random in accuracy - depends on the supplier's/manufacturer's interpretation of what constitutes a size. Quite frustrating.
My 1p worth.
