Options for Storing High Volume Custom Data

Summary:

Where should I store high volume data - Common Lookup, UDT or value Set

Content (required):

I have to store high volume of data(20000 rows) and then get these values called from a DFF dropdown. I am not sure which option would be more beneficial -

1. Store them in UDT and call that table from value Set or
2. Store them in Common Lookup and call that table using Value Set or
3. directly store them in Value Set as Independent Values?
