Terry, it's usually better using that other fingering. But beginners generally have weak little fingers (that's a weak 4th finger, not fingers which are all little and weak.. :), so your original fingering might be useful in that case. And your original fingering can also be used for an alternative G chord which goes 320033, using 2nd finger on bottom E, 1st finger on A, 3rd finger on B and little finger on top E - try it and see what it sounds like.
