Unless you are terribly concerned about theft/loss then you're still better off going with Apple's out of warranty replacement. With this you pay a monthly premium no matter what and then still have to pay a deductible if you need a replacement. With Apple's out of warranty replacement you're only going to pay if you need the phone replaced.
That being said, I did have a similar insurance policy on a phone several years back and they replaced it for $50 when it fell off of a belt clip (lame, I know) in the rain and I didn't notice it was gone until it was too late.
With Find My iPhone I'm not too concerned about losing my iPhone (as I'm usually very careful with it), and it's just not worth the extra fee to protect against theft.
