They ported two into 5e. One indirectly and one directly.
They ported Kingmaker indirectly, by releasing Kingmaker as a PF2e hardback and a supplemental 5e book that had the monsters as such for 5e.
They ported Abomination Vaults directly into 5e. It is currently available in hardback.
If I were to have my choice of any Adventure Path out there with a group that had never played any of them...I think it depends on how long I expected the campaign to go.
I'd probably choose Paths of Immortality (if you have all the modules, most probably do not) or Rise of the Runelords.
Alternate choices probably would something like Kingmaker, Skulls and Shackles (pirate themed AP), Wrath of the Righteous (Crusader type campaign), or War for the Throne (GoT type?). Abomination Vaults (Dungeon Crawl) is not a bad choice either.
If I wanted to run one I haven't run yet I'd run one of the following, Return of the Runelords, Seven Dooms for Sandpoint or if going for a D&D one I haven't ever run but want to one day...Age of Worms.
Seven Dooms for Sandpoint is available. PF2? Is it good?
