I have Parrot installed, but honestly I don't use it much. I like it better than the one with the O/S because I find it easier. Sounds good to me but I have not compared it to another phone.
Parrot is the most user friendly. It has a good Cascades implementation. Only gripe is the fact you can only replay the recordings in-app. I haven't found a way to export the recordings without upgrading, if that function exists at all.
I use the app Voice Recorder for exportable files, but the free version is very naked.
Whatever you chose make sure you disable the voice command activation on the mute key. If you do not you will definitely nuke your recordings. Any time this button is pressed during a recording session any resultant voice recording will become corrupt, regardless of what application you are using to record.
