I had a Seidio Active case and holster for my Note 2. It was really nice. There were a couple of things I didn't like about it:
1) the soft black inner rubber part felt almost greasy when you hold it. It was kinda secure and yet felt a little slippery.
2) with the kickstand, you can't reverse the phone in the holster and have the screen out, which I like to do on occasion.
The Seidio Active replaced an OtterBox Defender that I found entirely too bulky and heavy. Of course, the Note 2 was well protected, but I didn't care for the additional bulk and weight. I didn't care for the built-in screen protector either. While it seemed very well engineered and worked very well, I never quite got used to feeling my finger touch the screen and then touch the surface of the device... a double touch. Also, the power button was very hard to push and when I did, the case creaked and my finger hurt! And lastly, the hole in the screen protector for the home button tended to be a bit of a dust vacuum.
