I think that the question requires qualifications.

If you are very proficient with a rotary, then there isn't a reason to change. Skilled rotary users don't need a DA polisher for most tasks. Of course there are always exceptions such as tight areas, bumpers, etc...but assuming that the polisher will be used for standard panels a rotary is always more than sufficient.

If you aren't skilled with a rotary, then obviously the flex is the machine of choice.

The downside of the flex currently is a lack of any different backing plate sizes. To name the same cases that I did for the rotary such as tight spaces, bumpers, etc...the flex isn't necessary as flexible as the PC.

So...what is the answer? I think that you need either a rotary and a PC, or a Flex and a PC. That way no matter what comes your way, you are sufficiently equipped. Your choice of machine will vary based on your skill with either. I don't think that the flex is sufficiently awesome to make skilled rotary users put their machines away for an orbital. At the end of the day, the rotary is still king as far as gloss level that is achievable and correction ability.
