I've used both and prefer Skada right now; it seems more lightweight than Recount. What bugs me the most though is the discrepancy across addons, and sometimes even the same addon. For instance the other night my Skada showed me at around 190k DPS on Norushen. Someone else's addon (not sure if Recount, Skada or another) showed me at 209k. I've never found any damage meters to be consistent.
