The clearest difference is review sentiment: F at 57% against Secure by Frontier's 15%. F also leads on ads (none vs shown) and rating (4.6 vs 4.2). Secure by Frontier's advantage is monetization model (free with in-app purchases vs subscription). On price, in-app purchases and device support there is nothing between them.
