Hi jerryratpack,
Interesting point you have raised here so I have checked with my favourite chord finder chart at: http://www.all-guitar-chords.com/chord_name.php
According to it the chord listed as Gmaj7 xx2345 is not a chord at all and as you say the reverse xx5432 (which is easier to play) is in fact Gmaj7. Also the three other alternative fingerings I gave in the other Gmaj7 thread are correct.
Perhaps the more technically minded members will pick this up and add their comments and if the listed fingering is incorrect I am sure that Per will amend it.
Thank you,
Roger
