It also looks like we only know of 33 systems with 20+ gas giants. If you can find one with anything in the 20s, it's well into the "less than one in a million" category.
In fact, it also looks like only 223 systems have 17+ gas giants. That's 223 out of 49,241,850 systems in the data, so 0.00045%... which is like 4.5% of one percent of one percent. So pretty darn rare!

The top 3 stars are all Herbig AeBe stars, and I'd wager most of the rest on Orvidius' list above are Herbigs too. So that seems to be your best bet as a go-to star-type for large numbers of gas giants.
