Guitar Playability is, of course subjective, to a point. The width and shape of the fingerboard - the depth of th neck - the scale of the neck (that is the distance between the frets) - the height and weight of the strings - are probably te most important variables for the 'feel' of a particular guitar.

Your Baby Taylor has a different scale from your Alvarez, assuming the Alvarez is full size - that will make a significant difference. I would also bet the width is different - these two things alone could expalin the Taylor's feel being more attractive to you (smaller scale, a little less width can make it easier for a small hand to get around).

A guitar neck ought to fit the player's hand. The whole thing is very subjective!
