Pros
Pro Warriors and others have comparable power to spellcasters
While magic stays relevant and valuable, spellcasters no longer reduce all other allies to the equivalent of henchmen or "meatshields." Warriors and others without magic are closer to equals than ever before and in their own specialties can surpass magic-users.
Pro Three-action system for facing foes or hazards
When in danger, you can do 3 actions and a reaction every set of turns. Many actions only require one action to do while others use up two or three. For example, you could attack three times on your turn, but you'll take an increasing penalty on the second and third attacks, which encourages diversifying your tactics.
Pro All the rules and foes can be viewed free online
The role-playing game uses an open gaming license and all rules content can be easily viewed online, such as at the Archives of Nethys website. The free Pathbuilder2e app for Android makes character creation effortless and many other free resources and gaming aids exist. You can play Pathfinder 2nd edition - if you wish - for the grand price of free, though buying PDFs and books is a real option.
Pro High-level combat doesn't slowdown or become "rocket tag"
Unlike Pathfinder 1st Edition, combat doesn't become drastically different in the time it takes to finish as you advance in power. Nor does it become possible to end a battle against an equal foe with just a lucky first attack via spell or whatever (aka "rocket tag").
Cons
Con Players may undervalue small bonuses
In this game, every +1 you gain means a 5% greater chance of success and a 5% greater chance of a critical success, and it isn't easy to stack bonuses. But players will not intuitively realize how valuable even a small bonus is in the game, and may feel unsatisfied that they don't have big bonuses to actions.
Con The rules complexity and overall learning curve will take longer to learn/get into
There are a lot of different conditions, and many feats to choose. You really need to sit down and learn the rules as a GM, and new players may need to limit themselves to appropiately take the time to learn.
Con As much a revolution as an evolution of Pathfinder 1st Edition
Pathfinder 2nd Edition is recognizable as the successor to 1st Edition but makes many changes. Whether this leap is too far, too small, or just right depends on how one feels about the earlier version of the game and the designers' goal of making the game easier to get into and faster to play while keeping player characters highly customizable and tactical
Con Spellcasters no longer dominate the game
Spells no longer eclipse mundane methods to victory, which can feel like a nerf to magic lovers. While magic stays relevant and valuable, spellcasters no longer reduce all other allies to the equivalent of henchmen or "meatshields." Warriors and others without magic are closer to equals than ever before and in their own specialties can surpass magic-users.
Con Power gaming is harder than before
Those who want to fulfill a power fantasy and take advantage of every rules loophole to create a highly specialized legend may be frustrated. Pathfinder 2nd Edition has a higher floor, so-to-speak, and a lower ceiling when it comes to relying on your system mastery to optimize a character. You can do but it will be harder and you may gain less of an edge than you could in Pathfinder 1st Edition
