Left and Right together: both tigers do not seem to emphasise anything in particular.
In judgement: both poems refer to ‘tigers’ (tora), with the Left having ‘a valley where tigers lie’ (tora fusu tani) and the Right ‘isles where tigers lie’ (tora fusu shima). These seem to be an attempt to differ from the standard ‘meadow’ (nobe). Saying ‘valley’ or ‘isles’ makes both poems sound modern. They are of the same quality.
