Where the libraries tie
On raw actor inventory, this one is close: Arcads advertises 1,000+ AI actors with emotion control and custom face generation; Fastlane ships 1,000+ pre-made hyper-realistic UGC characters. Both clear the realism bar, and anyone telling you one library is categorically better is selling something.
The tiebreaker is what the libraries cannot show: Fastlane also carries 2,000+ videos from real human creators on Pro, for the campaigns where an actual person beats a synthetic one. Arcads is all-AI by design.
