Both are comedies with a great over the top male leads who are quite devious and hiliarious. If you enjoyed the performance of either one, you'll most likely quite appreciate the other.
pretty similar imho
# office environment: lawyer vs real estate agent
# different cases span over the episodes
# main leads = unbeatable
# some very similar cases/plots if you watch all four seasons of both
in short if you like Legal High im sure you will like Ie Uru Onna as well.
