For me with technology improving rapidly I don't see that much change in sound and styles quality in TOTL arrangers,.........where years ago every NEW release was really a major improvement. Changing & Buying New gear is becoming a longer and longer in between process if you really think about it.
And then you always have to ask yourself "DO I REALLY NEED THIS"? and "WILL IT MAKE ME PLAY & SOUND BETTER"? ......Most times not.
But if it makes you feel good go for it.
