Halogens have a warmer, more natural light but run very hot, especially on high
intensity. Think those old torch floor lamps, especially before they cut the
bulb back from 500w to 300w.
Fluorescents have a much cooler light and use less electricity, hence they run
cooler but don't look as well with natural wood cabinetry. You can't dim these
either.
Halogens in a bar type fixture can address some of the heat concerns that the
puck style lights have. Xenon lights have similar color to halogen but run a bit
cooler.

On the plus side, fluorescents are more energy efficient, cooler
running and provide much longer service life. They're also available
in a wide range of colour temperatures (e.g., 3000K, 4,100K, 5000K,
etc.) which, depending upon your decor and personal tastes, could be
another plus. Linear fluorescents distribute light over a wider area
and this light is soft and diffuse, so there are no harsh shadows (an
important consideration when you're working with knives and other
potentially dangerous instruments). And if you prefer a lot of light,
they're the only game in town.
Halogens offer a pleasant, warm light and superior colour rendering.
They also provide more punch and sparkle, and a little more visual
interest due to their higher contrast ratios (shadowing).
I opted for low profile T4 fluorescents because they're four to five
times more energy efficient and because I prefer a lot of working
light. These particular lamps have a high CRI (colour rendering
index) of 86 and a colour temperature of 3,200K (just slighting above
that of halogen); Overall, I'm pleased with my choice.
There is, however, one notable drawback. I have highly polished
granite countertops and the bright reflections given off by these
lamps detract from its overall appearance. My sense is that the
reflections generated by smaller halogen pucks wouldn't be quite as
noticeable (or objectionable).
Cheers,
Paul

Halogens are small, bright, hot, and slightly more efficient than
regular incadescants.
Florescents are larger, cooler, dimmer and a lot more efficient
than regular incadescents.
Preferred for what?

Halogen are hot and 75%-90% less efficient than T8 flourescent, unless
electricity is of no concern its obvious what is best. Warm white
bulbs have a pleasing color.
