I’ve got a few Santana records so I’ll rank what I own:

1. Abraxas
2. Santana
3. Santana (III)
4. Caravanserai
5. Amigos
6. Borboletta
7. Marathon
8. Festivál

I am only missing Welcome and Inner Secrets from their peak period, Welcome would slot in around 5 or 6 and Inner Secrets probably at the bottom. Also missing a few live albums but I’m not keen on them.
