Which Jointer Feature is Superior?

Apologies for another jointer post… there seems to be many. I’m about to purchase my first jointer (Grizzly) and I need to buy from Home Depot. After research, it seems the benefits of both helical heads and parallelogram beds are apparent, so I committed to adding them to my wish list. That said, HD doesn’t sell a Grizzly jointer with both. So for those with jointer experience, if you had to keep one of those features, which would it be?
