For millions plus rows, the queries get crazy slow. If your jsonb field contains lot of data, JOINs on toast storage tables takes chunk of the query times. My 2 cents: Best to keep data normalized and in separate columns. If you gotta keep data in jsonb, keep only the data that you don't need to query on. Anything you need to query, you better put it as a column. You'll thank me later.
