Well, I'm not sure what "Military grade encryption" is but obviously it sounds good. I found this on one of my trusted sites;
What Is "Military-Grade Encryption"?
In any case Enpass has all of the same features including AES 256 bit encryption.
In the end there's not a lot of difference between basic functions, they all do essentially the same things just in different ways. It really comes down to what you like/don't like, what you need and what you can afford.
I have over 250 entries in Enpass and I couldn't do without it.
Make sure which ever one you pick allows you to add notes to your password entries, I have a lot of those eg my bank account. I have login number and password plus a note with Telephone Banking PIN, three Security Q & A's, Debit Card and Credit Card PIN's ect, ect.
