First of all, they are called “Daleks”.
Second, they are not androids. They are squishy, one eyed tentacle aliens living in robot suits.
Third, as much as I love the Borg, the Daleks would win, without a doubt.
They have time travel capabilities on par with that of the Time Lords, whereas the Borg only used it once, unsuccessfully.
The Daleks would wipe out the Borg before they even existed.
