Verdict

  • FormFlux is freemium; PlainInvoice is free.
  • Neither product has user reviews yet, so there's no rating data to compare.
  • PlainInvoice has more upvotes (25 vs 3) — a sign of more traction on LetsLaunch, not a quality verdict on its own.
  • PlainInvoice has already cleared LetsLaunch's survival bar; FormFlux is still inside its launch window.

None of this crowns an outright winner. FormFlux and PlainInvoice both compete in Productivity, and the differences above are facts to weigh against your own use case — not a recommendation either way.
