I switched from tenor to concert and glad that I made the switch. After playing a soprano I decided that I wanted a bigger sound and more expansive fretboard. Decided to try the tenor since I figured a concert wasn't much of a change from the soprano. Well, I found easy stretches on the soprano became difficult to nearly impossible on the tenor in the lower positions. I was also surprised at its much greater string tension, and, as a result, significantly increasing the required fretting pressure (over the soprano). Bar chords on the tenor became a real challenge above the 5th fret. Finally, I really missed the brighter, harp like tones of the soprano - the tenor was a bit too mellow and guitar like for my taste. (It seemed to loose much of the tonal qualities that originally attracted me to the uke.) So, when the opportunity arose, I switched over to a Concert and am really happy with this sized uke. It has more fretting room than the soprano but not the drastic stretches of a 17" scale tenor. Finger pressure makes playing more comfortable and less tiring, and it's tone is closer in quality to the soprano than the tenor; a nice balance between those two sizes.
ONTOH YMMV
