I don't think past winners in a state is very relevant, but that's just me. 'You do you' as they say.
If the jackpot size is important to you then go with PB for now. The odds are the same for 20M or $120M. Personally I ignore the jackpot size and focus on the lower tier prize of $1M + multiplier. By doing it that way I can choose either game as whim dictates.
Just food for thought. Good luck on whatever you choose!
