[Fantastische Hure]

Who wins?

Dumbledore was stated multiple times to be the most powerful wizard of the era iirc, so he still most likely wins in terms of magical power regardless of the wand, though he may lose due to being less likely to use killing curses than Voldemort.

What about Dumbledore vs any of the four founders? Let's say Slytherin.
