I think it's not so much as someone insulting the brand or model of an arranger someone has spent the time to research and purchase with their hard earned money, but when such criticisms (sometimes unnecessarily blunt) are perceived (wrongly or not) as an insult to some one's choice of said instrument as being less than wise.

No arranger is perfect...no buying decision is either, but not too many like it pointed out (in a sometimes flippant manner...maybe an attempt at dry humor, but certainly rarely understood by everyone) on a public forum that they are being made to look like they are inept, or even fools, for buying a particular brand compared to another poster's obviously wiser (to them) decision.

We must always remember (me included) that our needs are sometimes different...sometimes to the point of being polar opposites.

It is perhaps better to focus more on identifying with another arranger user than on comparing the differences, although the latter does have a certain amount of value when done in moderation.

My opinion of course.
