I would prefer QGMLWY for these reasons:
* ZXCV in same positions as QWERTY
* looks just perfect for Latin language speakers.
My native language is Portuguese... and we use vowels a lot, in every syllable you will find at least one vowel. So, QGMLWY puts all common vowels in the home row, not under the pinkies, which is definitely the right thing to do. I never tried Colemak when I saw that A and O are under the pinkies.
I've provided configuration files for Linux which allow Carpalx layouts be selected via keyboard configuration applet.
I've also created a keyboard emulation for the wonderful Miniguru, in case you would like to have arrows as IJKL.
