Longtime D&D player (all versions since AD&D1) who decided to jump into Pathfinder 2nd at launch. I actually subscribed one issue early to Adventure Path to get the grandfathered discount.
I am currently subscribed to:
Pathfinder Adventure Path
Pathfinder Lost Omens
Pathfinder Adventure
Pathfinder Pawns - (Just added this for the upcoming Bestiary Pawns)
Pathfinder Rulebook
Pathfinder Society - Free
Pathfinder Accessories
The subscription discount may not be quite as good as Amazon, but getting the free PDFs is a great value, and helps mitigate that. I really don't have a local store, so subscription is also good in that regard to get the newer releases.
Here are my thoughts on each.
Adventure Path - Already familiar with this concept from D&D 3rd (from Dungeon) and Pathfinder 1st edition. Like the concept and glad they will eventually support Age of Ashes with Pawns and hopefully a map pack.
Lost Omens - Disappointing the two books are so small. Lot of player content in the character guide. I feel these could have been one larger book, but maybe the book size on the Core books has spoiled me?
Adventure. I missed there was a map pack for Fall of Plaguestone and had to go track it down at a retailer. Since there are so few releases, I sorta wish the map was included in this subscription.
Pawns. Don't have the new ones yet, but have used in the past. Useful.
Rulebook. Big books, big content. Hope the Gamemaster guide is good. Glad we are getting errata. Would like to see the PDF's updated with the errata before a second printing of the physical books.
Society - Not playing Society, but who doesn't love free adventures?
Accessories - This is perhaps my one actual regret so far? Here are my thoughts.
Combat Pad - Useful
GM Screen - Useful, but you did 2 versions at launch and I didn't get to choose? Now you are replacing it with a third screen in January?
Character Sheets - Worst product in the whole line. Great concept with class specific sheets, but has errors for Fighter and Alchemist. Not printer friendly, not form fillable for PDF. Please fix and update the PDF at least.
Condition Cards - Mildly useful - no PDF of cards
Critical Hit Deck - Haven't really used yet, but seems brutal for PC's - no PDF
Critical Fumble Deck - Haven't really used yet, but seems brutal for PC's - no PDF
Aside from the Combat Pad, I could probably have done without all the accessory content so far.
The upcoming releases raise a concern for me?
Advanced GM Screen - A third screen?
Bestiary Battle Cards - Potentially useful, but no errata and more expensive than the Bestiary itself?
Spell Cards - 5 decks being release in January along with the GM Screen and Bestiary cards? Is that really 7 products in January? Will these contain the errata?
