I have acces to 2 pfd and like them both for different reasons:
1) Stohlquist wedge E - made in the USA and easy to get your hands on. ~ $100 at most places. REI is your best bet. Bare bones. Lets you move your shoulders easily and when you do swim, the neck does not chock you as some pfds do. Has only one small pocket that doesn't really hold much more than keys. I use this as my summer pfd, as attaching a stobe or a hydration system is not as easy as it should be. I don't use it in winter.
2) Serratus Aphrodite - This is my winter pfd. 4 pockets provide enough storage for anything I want. Hydration and stobe attach easily to the back. This is a warmer jacket, but still allows for full rotation. Buying the woman's version meant that there was more room for my chest and shoulders to move freely. I used as a race jacket for 2 years, but switched up to the Stohlquist for summer stuff 2 years ago. Don't remember the price, sorry.
If I was to do it again, i'd just get a Kokatat Orbit Tour. 2 pockets and plenty of movement. Ability to attach hydration/safety easily and very reflective. They run about $150 here in Vancouver. I think LL Bean sells them in the US for about $140.
If you have acces to REI, check out the Astral Bouyancy Hybrid.

Good luck with your search.
