Usually try to stay clear of "x vs. y" arguments, but since this is list based, I can spare myself a nerd argument by making quick points and let others do the arguing. Anyway, taking the paradigm/trope of the Reapers and contrasting them with their counterparts (or closest to counterparts), I'll make the following pitches:

-Reapers vs. Shadows (Reapers win) -Reapers vs. Cylons (Reapers win) -Reapers vs. Shrikes (Reapers win) -Reapers vs. Scrin (Reapers win) -Reapers vs. Brain Spawn (Brain Spawn win) -Reapers vs. Flood (Reapers win) -Reapers vs. W’rkncacnters (W'rkncancnters win, assuming there's more than one, which I do) -Reapers vs. Shivans (Shivans win) -Reapers vs. Hydrogues (Draw) -Reapers vs. Metarex (Draw) -Reapers vs. Xel'naga (Reapers win unless energy creatures can harvest their genetic material) -Reapers vs. Aparoids (Reapers win) -Reapers vs. Replicators (Reapers win in short term, Replicators in long term) -Reapers vs. Borg (Reapers win) -Reapers vs. Seraphiem (Draw) -Reapers vs. Tyranids (Tyranids win) -Reapers vs. Eqbas (Reapers win) -Reapers vs. Nephilim (Reapers win) -Reapers vs. Daleks (Daleks win) -Reapers vs. Mala'kak (Reapers win) -Reapers vs. Psychlos (Reapers win) -Reapers vs. Combine (N/A-rules of engagement are too different)

Obviously other parallels can be drawn, and I can draw out the paradigms even further. Still, have fun. ^_^
