Hmm, I definitely disagree based on my experiences. I think the lack of timeout with a limit on attempts is far nicer, it works reliably for me in nearly every case except sometimes in the winter (which affects other fingerprint sensors I've tried as well), and the position on the back is ideal for me in almost every position I use the phone. I can easily pull it out of my pocket and activate it one-handed without feeling like I'm holding my phone precariously.
