Ive flown all 3 and metros about 20kts faster than J31 and 500kts faster than L410.
Its headroom is much lower but you dont trip over the
spar half way down, seating is 1+1 so you dont get stuck next to some big fat b
and evry seat is a window seat.
id go with the metro every time. Operated them in Germany for 2 years and were very reliable
