This is my first iPhone, but the Lifeproof case has been just fine for me. Admittedly I am on the water frequently, but compared to other protective cases they went out of their way to use high quality optical glass and it shows in amazing pictures. The screen sensitivity is really no big deal at all for me. Yes, there is a slight occasional separation from the glass, but easily disappears by smoothing it once over your thigh, and even if you don't, the screen sensitivity is just fine. It has had minimal effects on the sound quality incoming or outgoing, but it does have some. If you have no reason at all for water or other kinds of significant protection, don't buy it. I don't intend to take it off on a regular basis, and you do need to pay attention to putting it together, but give me a break....it's not that hard. I took mine off, recleaned the screens and put it back on in about three minutes. The videos simply give you some hints about putting it on.
