I'm using this brand for S7E, coverage is good and I've not compared with clear coat, but it has a tpu feel to it. On the good side it looks as though you're not using any SP as it's edge to edge.

I am using this screen protector with spigen rugged armor. The edges will lift slightly. U need to slowly tug it back in. But overall, I am happy with it.

get the spigen neoflex screen protector if you using any spigen case. works perfectly

I heard from one of the forumer sharing the x-one ultra screen protector video that it's extremely case friendly, the video also show UAG case testing and fit nicely!

SP is an  individual choice. Some are cheap while some others are pricy.
Here I see many justify why is a must to spend up to rm200 for a SP. Well if this make them comfortable just go ahead.
Personally I will not spend money on such SP anymore. As it comes with the phone I tested Samsung SP but I had now removed it as I still prefer feel of the naked display.
I had been warned many times I am being foolish by not applying any protection. Well in my past 8+ years using so many smartphones most of them I do not have SP applied. I had yet experienced even a hairline scratch. I am a very careful person and take good care of my phones. Pessimist will say " you just wait for an accident" !! My phone is always protected with a flipcase and I use only a backcase with phone in car with it on a holder.
Furthermore I rarely use a phone more than 6 months and I don't see point to spend extra on the phone. Even cases I buy cheap types.
Touch wood here - I had never ever even drop my phone before. Most drop cases I believe is due to user carelessness and habit to use phone single handedly. Unless I am taking calls I always use both hands - left to hold and right index finger on display. Personally I am shock to see many users using their smartphones single handedly  while standing up on a moving LRT and they had themselves only to blame if they drop the phones.
