Well this is my opinion.

 
Well this is my opinion,  standard guitar tuning is the worst tuning I know, the only use for it is if you play in a group or band with other musicians, or if you naturally have a high pitched voice.

 Dropped D tuning is a little better.
 Double D Dropped tuning  even better. 
 D A D G A D is a beautiful modle tuning , great for songs and tunes in D.
 D A D F# D another beautiful tuning , open D, great for fingerpicking,  slide playing, dead easy for strumming.

 And my favourite tuning of all time, easier on the voice if you are a singer ,  kinder on the fingers, and far less stressful on the guitar, this is also called the new standard tuning.
D# G# C# F# A# D #

Anyone else have a favourite tuning that's not Standard tuning.
