Ideally you want 5 (or 7) identical speakers for a uniform experience. This also helps with setting a proper crossover point for the subwoofer and ensuring timbre match. Some who don't research the topic might also be inclined the place the surrounds in the rear while they belong at your side slightly elevated beyond ear height. A vast majority of your dialogue will come from center channel and music from front l/r so you are correct that the front soundstage is usually larger, the surrounds are meant to introduce immersion in a subtle way. When you have rain on a movie for instance and it sounds like you are literally standing in it, you know you have it right. To each their own...but sound bars and surround in a box is not really a good starting point to judge the experience in my opinion.
All I need is my Sega's CD QSound.
Proper set up is key. Your receiver should have set positions for the dimensions of your room. Read the manual of your receiver like there is going to be a pop quiz on it. Some receivers have settings for "small" "medium" and "large rooms", others let you input the sq. footage. A good receiver isn't cheap, so utilize that equipment for the best sound possible. Totally worth the time to tweak the settings.
I do the whole seven speaker thing, but I have to say I have a friend who has a sound bar that really does a fantastic job. Maybe it's the size of his theater, but the bar does an incredible job of putting out "surround" sound.
Good part about calibrating your sound system is that I find it something that is fun to be obsessed with. Nothing like hearing the THX theme full blast in crystal clear quality.
