 I think of PDAs as a hybrid between Accounts and UTXOs. They are account-like in some ways and UTXO-like in some ways.

 PDAs use the terminology of the account system. (account-like)
 PDAs are declared and mutated like storage items or storage maps. (account-like)
 Each PDA has its own id/address that is determined at creation time based on seed info like a signer or tx hash. (utxo-like)
 Transactions explicitly state which PDAs/UTXOs they access so the TPU knows which are parallelizable and which must be serialized without caring anything about the execution logic. (utxo-like)
 Transactions state which PDAs/UTXOs are read-only / peeks vs which ones they will mutate / consume (utxo-like)
 PDAs are mutable and reusable and keep the same storage address the whole time. (account-like)
