Having the need to store and access blobs which type of storage account is the most appropriate? Both types (general purpose and blob storage) seem to support blobs and in addition to this general purpose accounts allow selecting default or premium performance while blob storage accounts allow only default performance but on the other hand they also allow selecting the access tier (cool or hot).

In the end I find unclear what would be the best option.

Microsoft's guidance on this (as of 7/13/2018) recommends using General Purpose v2 (GPv2) Storage Accounts over Blob Storage accounts for two reasons I recently discovered (there might be more):

  1. They offer more flexibility in terms of what you can store and do with them (Queues, Tables, Files and/or Blobs vs just Blobs). Ref: Microsoft Azure Documentation - Azure Storage account options

    Microsoft recommends using general-purpose v2 storage accounts over Blob storage accounts for most scenarios.

  2. There are more integration options with GPv2 accounts including Azure Function Triggers via Event Grid. Ref: Microsoft Azure Documentation - Azure Blob storage bindings for Azure Functions

    Blob-only storage accounts are supported for blob input and output bindings but not for blob triggers. Blob storage triggers require a general-purpose storage account.
