Weathered Yagrush (i100) has better itemization than Thyrus Animus (i100), so it's the better choice. If Novus (i110) customization is worth a damn, it might be better than Yagrush (i110) but we'll have to see. That said, Yagrush is almost guaranteed to be a damn sight faster/easier to obtain than any Novus weapon owing to the atma and myth farm, regardless of what the Novus questline includes.
