Guitar Chord or Guitar Scale - What is important to learn?

Guitar Chord or Guitar Scale - What is important to learn? yeah what about you? Chord is note composition, it's come from Guitar Scale. Now what is more important to learn? if you are a seriously guitarist who want to play or get a real think about guitar, SCALE is number one. If you have more knowledge about Guitar Scale, you can make your own Chord. This is very simple, okay let see what i talking about.. one of my favorite guitar lessons
G major Guitar Chord is :

|----------------------------------2-3(g)-5-
|------------------------------3-5----------
|------------------------2-4-5--------------
|------------------2-4-5--------------------
|---------2(b)-3-5--------------------------
|--3(g)-5-----------------------------------

See at the guitar tab : major Scale is 1-3-5-7 = 3(g) 2(b) 3(g)
and G Major is :

|----3--------
|-------------
|-------------
|-------------
|----2--------
|----3--------

And the note composition is 1-3-1
it's easy right?
