zerker or regular pure

Well should I stay a regular one defense pure or move onto a zerker pure already and get done with it.

With zerker pure I would stay at 52 pray and 45 def, no higher in either, 1 summ, and other stats may be moves 80+ depending on ideals.

Regular pure 1 def/1 summ/ max is 52 prayer
Other stats may vary

Well what do you think I should do?

Please give logic with your ideas such as

"I think you should be a zerker pure because..."
ex: Zerker pures are more fun since you get more kills.
