Use Facebook's "Paper" app if you want messages built in to your client. It is also a better Facebook client in general, though it needs some tweaks for iPhone 6/6+ to make it easier to use one-handed. After getting an iPhone 6, I switched back to the regular Facebook app because Paper has notifications in the upper right hand corner which is usually opposite of my thumb.
If you are on a 5S or older or don't care about one-handed use, just use Paper. It also performs really well compared to the regular client. It was very performant even on my 4S, while the regular app was so slow it was unusable.
I actually like the separate Messenger app for one reason: you can use landscape mode. Neither the regular Facebook app nor Paper do landscape mode.
