Every instrument has its own character. I fully believe that an instrument has a living soul (as does everything else) and from this derives its character. It sounds to me like you are just not compatible with this particular instrument, rather than that it is too good. I have owned various quite expensive guitars...Martins mostly...but I have a Yamaha dreadnought that is just such a joy to play, even though I've had Martins which cost 4 times as much I still like this Yamaha the best...so far. There is one type of situation where an instrument can be too good...if it's in the hands of someone who mistreats it and doesn't appreciate it. I've seen cases like that. Sort of like seeing a woman of great character in the company of the neighborhood jerk...or vice versa. I've seen that too. For a player who respects the instrument and treats it accordingly, I doubt that it can ever be TOO good, but maybe it's just not the right one for him/her on a personal level. Go with what you feel, and don't worry about brandnames.
