The Do335 was fast. But as a pure fighter once you get the DB603 and Jumo 213 engines, wich are crucial for the Do335 to work, you can use it on single engined fighters like the FW190D, or better still the Ta152. When you're facing Mustangs over home ground, dogfighting ability is more important than pure speed or range for fighters.
What about as destoryers? The Me410 was food for the P51 and Tempest.
