First let me preface this by saying that, as one who uses BOTH SMFs AND arranger styles during a gig, I do not mean to offend anyone with any of the following comments ... that being said ...

As many have said here, there is room enough for ALL of us, using WHATEVER means we want, to satisfy our clients and ourselves ...

I liken Scott using the arranger mode to when I play a tune using the arranger styles(not that I have his talent) -- I feel like I am back in the days of the band in NY - playing the top tunes - OUR way ... when using a SMF, I feel more like a DJ, spinning the original record, except that I am playing and singing over the backing track, which of course personalizes it to a degree ...
Truth is ... I would MUCH rather be working with the guys in the band again ...
