Authenticator App ™'s advantage is ratings volume (25K vs 2) and chart position (#133 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Authenticator App ™ sells 2 in-app purchases, starting at $9.99 per month and spArxx.io sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
