Honestly I've bought cheap press releases, and I've bought expensive ones (though no $200 ones, that a bit steep).
The #1 difference is article quality. But NOOOO article is worth $195, now is it?
The #2 difference is distribution and the hustling they do to get it in Google News, etc, etc. I'd pay an extra $20 for this, no problem.
So IMO a $200 PR is a load of bullcrap 99% of the time. A $50 one, sure. But I personally have no need for bells and whistles, and my niche isn't going to go viral. So $5-$50 is my range.
