An undocked Switch blows away every other handheld.
Other than that, I'd say the 3DS. The OG Game Boy will always hold a special place for me, though.
Since I already answered this question for Switch when favorite Nintendo console was discussed, here are my top 5 Game Boy games.
1. The Legend of Zelda: Link's Awakening
2. Metroid II: Return of Samus
3. Kid Icarus: Of Myths and Monsters
4. Pokemon Red/Blue
5. Final Fantasy Adventure
