A single flute cutter can be stiffer if the grinding design permits.
Resistance to deflection is a good property. Most 2 flute cutters exist
because of dynamics. A single flute OGee, e.g. will blow itself up at
25,000RPM.
Single flute bits have balance problems and are rarely found on cutters
with diameters much > than the shank.

1. single flute cuts rougher but heat up less.
2. single flute bits are usually plunge bits

A single flute on a straight bit allows retention of more "meat" on
the shank - resulting in a stronger bit with less deflection.
A single-flute bit requires a slower feed and/or higher spindle speed.
More flutes permit higher feed rates and/or lower spindle speed. When
I have a choice I opt for three flutes, with two flutes as my second
choice. I've found that more flutes produces a smoother cut, perhaps
because with the spiral cutters I use, one of the flutes is always
bearing against the side of the cut.
When cutting with a V-bit, three flutes allows "parking" the bit
briefly without enlarging the cut at the parking spot.
The bits may be intended to produce the same-shaped cut but their
behavior is different. Choose the bit that provides the behavior
characteristic(s) you deem most important for the job you're doing.

Oddly the single flute bit offers better performance than the 2 flute bit.
Per the Amana tool site,
Single flute allows for faster feed rates, greater chip clearance and
maximum stock removal.

I asked the same question after buying some single flute at an auction. I
was told they were for corian, which makes sense since I bought some corian
at the same auction.
