Which is the strongest boss in Tibia?

Question

There are more than several powerful bosses in Tibia. I would like to know which ones have more life which gives more experience which is more difficult to kill?

I don't think it is a duplicate. Author asked about the similar thing, but taking into account few different aspects, so the answer potentially can be wider than in the mentioned question.

An edit should be made to the question. Strongest and Hardest are similar. He's asking 2 different questions: Which gives more experience? Which is more difficult to kill? His question should be changed to- What boss gives the most experience, because of the terms on which is the hardest was already answered and would be a duplicate.
