As a site carpenter whether I use imperial or metric usually depends on which way round I’m holding the tape measure, ie, if I’m measuring from the right-hand side of the tape it comes out as imperial, but if I’m measuring from the left-hand side of the tape comes out metric.
As a consequence I often mix imperial and metric dimensions for the same item.
Personally I generally prefer imperial as I find the numbers much easier to remember.
Of course with imperial measurements I’m including the indispensable “gnat’s bollock”, e.g. thirteen and three-quarters plus a gnat’s bollock.
There’s no such thing as a gnat’s bollock with metric.
