Yes they are good, but for routes like GNEs X21 they're arguably overkill. Even for the ANE X21/22 they're arguably overkill, though the extra power does probably come in handy with the extremely tight evening/Sunday/BH timetables - and they aid with fleet flexibility (especially with the ongoing debranding).
Given GNE don't seem to be quite as big on fleet standardisation, and don't have any other routes out of CLS that are too demanding, the B5TL is arguably the perfect vehicle for their X21.
