ADX Continuous Export to Delta Table - Public Preview

Delta has become a standard format. But as an Azure user, I am little confused about the many options I have to convert my ADX data in delta format now. I could 

• use ADX external tables to export to delta using continous export (> my favourite)
• use Data Factory pipelines which require a databricks instance to generate delta files from an ADX dataset
• use Data Factory flows to copy from ADX to delta
• use Databricks to convert ADX to delta
• use ADX to generate parquet and separate delta conversion from actual storage
• switch to Fabric because Fabric makes everything better
