Just look at what you need today and might in the near future. I don't regret having all the HDMI inputs as we have a need. Cable, BluRay, Roku, Gaming, computer, etc. Although I have an automatic expansion/switch on our lower level system and it works great. Bluetooth is also something we enjoy having as both the PC and phone can stream effortlessly....aka wife and kids now can do it
Good calibration is key no doubt. Most of the nicer ones will do it automatically even. Just set up the mic on a tripod and go.
