My instinct is Breath of the Wild has better dungeons., but let's see.
Lowest Number Ranking:
- Hyrule Castle (BotW)
- Lightning Temple (TotK)
- Wind Temple (TotK)
- The Final Trial (BotW)

- Vah Ruta (BotW)
- Vah Medoh (BotW)
- Vah Rudania (BotW)
- Hyrule Castle/Gloom's Approach (TotK)
- Spirit Temple (TotK)
- Water Temple (TotK)
BotW: 1+4+5+7+8+9 = 34
TotK: 2+3+6+10+11+12 = 44

Breath of the Wild has better dungeons!
This is because BotW's worst dungeons (Vah Medoh, Vah Rudania, and Vah Ruta) are not even close to TotK's worst dungeons (Hyrule Castle, Spirit Temple, and Water Temple). The Divine Beasts can be short and the aesthetics can be identical, but at least they do not match the aesthetics of the Sky and Depths, or just consist of a series of ridiculously easy combat encounters in different rooms. And Breath of the Wild's Hyrule Castle is genuienly a brilliant piece of design work.
