Reapers vs. Borg

[Cosmic Ocean]

I love this debate so much and I’d like to see what you guys have to say about it.  Compare defensive capabilities, offensive abilities, speed, size of crafts, intelligence, level of technology, fleet numbers and so on as a starter. Good resources to use could be the TNG Technical Manual, the Star Trek wiki "Memory Alpha", the Mass Effect Codex and the Mass Effect Wiki.

Here are the parameters:

The Reapers and the Borg meet up in the Andromeda Galaxy in a neutral universe that is compatible with the science of both franchises. Both are at the height of their power.  Let's assume for the sake of argument that any civilizations in Andromeda during the time of this battle are pre-Type I on the Kardashev scale, thus having no influence on the war. The Borg do not have access to transwarp conduits/hubs and the Reapers do not have access to mass relays. The ultimate goal on both sides of this war is to totally destroy the other side and/or integrate the other side into their ranks somehow. This is a battle consisting of the entire Borg Collective and all the Reaper fleets.  Alright, let’s have at it!
