Well, Jungle Fury/Gekiranger's worked because it moved fluidly. It was one of the few times (Along with Ninja Storm's Lightning Mode and the Battleborgs) that a Megazord felt fast (To me, at least).

As for Lion Ha Oh, this one really does push it too far. A lot of large and tankish Megazords/Mechs try to get away with their brick like proportions with the reasoning that they're supposed to be large and beefy. But here? It's managing to look worse than Shinken HaOh since not only is it a brick, but it's also really dull in doing so.
