Hash Mode question

[ScTAE]

Hello,
in the hash mode parameters list I see these:
2500 | WPA-EAPOL-PBKDF2                                | Network Protocols
2501 | WPA-EAPOL-PMK                                    | Network Protocols
16800 | WPA-PMKID-PBKDF2                                | Network Protocols
16801 | WPA-PMKID-PMK                                    | Network Protocols


What are the differences between them?
I used to get a WPA handshake in a .cap file with aircrack (disconnecting a user and waiting for his reconnection), convert it in a .hccap file an then run hashcat with hash mode 2500.
Are some of these hash easier/harder to get/crack?
Thank you.
