POWER CHORDS VERSUS USUAL CHORDS

Now an than I use power chords. But still I prefer, even playing hard rock, to use regular chords.
You can play, I don't know if this is a good example, HONKY TONK WOMAN, starting in G, followed by C, back to G and D.
If you play this acoustic, you play "COUNTRY HONK' the acoustic version of Honky tonk woman.
But playing it Electric, you can use G C D, or use them in power chords.
When do you speak about using power chords ? I know them, but I like to strum, and at the same time, a kind of pulling the strings, or using little licks, like in E, kind of Crossroads, style.
So my question was, knowing the difference between the usual and power chords, who, or how many chordians prefer to play power chords, or like me, giving power to the regular chords.
You see the difference: using POWER CHORDS, or GIVING POWER to usual chords.
Maybe I am wrong, but if you have reached a certain level, playing guitar, you can do more variations, licks, other finger positions, like G, in stead of using my finger on the little E string, I can put that finger also on the 3th fret but on B.
