I don't like the PF 3-bet in hand 1.

I'd play hand 2 the same.

I find blind wars tough to digest. Most of the time, they are pissing matches where the winner & the pot size is determined by sheer luck (i.e. an unlikely pair spiked in a spot where the hand shouldn't be). I try to avoid unnecessary PF aggression without better hands (e.g. 98s).
