What is the best map at LHC in terms of EXP per Monster?

I've tried every map in LHC and out of all maps these:


Lion King's Castle - Under the Castle Walls 4/5 (6x Bearwolf)
Lion King's Castle - Tall Castle Walls 1 (4x Castle Golem)
Lion King's Castle - Under the Castle Walls 1 (7x Crocky)
Lion King's Castle - Under the Castle Walls 2 (6x Reindeer)
Lion King's Castle - Under the Castle Walls 3 (6x Blood Reindeer)

Are the best ones to train with a party.

I guess you didn't try out every map. How are you going to say Tall Castle Walls 1 with 4 Castle Golems, is better than Very Tall Castle Walls with 7 Castle Golems?
