It's all in what you call it. The guitaleles are made by various uke makers and marketed to uke players.
To clarify there are Guitalele style instruments - the Islander and Kanilea - made on Baritone uke bodies with wider necks. Most Guitaleles are built on Tenor uke bodies. They are all designed to be tuned A to A which makes the voicing the same as standard linear uke tuning. For some time I had a Yamaha Guitalele built on the Tenor scale. In my opinion the neck was too narrow and too short. Even tuned A to A there was just not sufficient tension on the strings. The neck was too narrow to chord cleanly. I now have the GL6 built on the baritone body, still tuned A to A. It seems to me the neck is pretty much the same width as a classical guitar neck. Unlike the Yamaha I had, the intonation is excellent, the string tension is sufficient and it is possible to play cleanly. The reason for using a Baritone body and neck size is to get enough string tension and get good intonation.
Previously I had a Mexican Requinto. That had more of a full sized guitar body but was built to play on A to A scale. I think it is based on a 3/4 sized guitar. The difference primarily was in how it was set up. It was basically a shrunken classical guitar with open headstock and tie bridge. It's all in what you call it. A Requinto is a Mexican folk instrument, but if you told me the same instrument was a 3/4 sized guitar, I wouldn't know the difference.
