If you want to play Nintendo 1st party, you have no choice but Switch. But if you want to play any of the many AAA games that release every year, you can do that on Deck. If we ignore that each is exclusive to the other's platform (i.e. Switch 1st party don't go to Deck, many huge games Deck can play Switch never gets), and just compare the average cost with sales of those "exclusive" games, you high quality games on Switch (Nintendo 1st party) cost way more than you high quality games on Deck (most AAA games Switch doesn't get).
