It is going to depend on what you want. Fluorescent is bright, harsh even, but a good choice for a kitchen that one might argue needs such clinical light to highlight where you forgot to clean etc. :-)
I changed mine to halogen when I re-did my kitchen. They look classier, more style, but I needed one every few feet and it was a bit of a pain to work out how to site them in a pattern that covered everything and found or avoided a nearby beam and suchlike. I like them but wish I'd added a few more if I am honest. Light is ok but not as much as I'd like.
LEDs are fine, it depends on the actual bulb you use as to the exact answers to your quest. My beef about them, and things do seem to be improving, but I'm unsure whether improvements will hit a wall, is a) cost, which is still high compared to incandescent, and b) the number of lumens one can get from a single bulb. For a kitchen where one tends to want light bulbs stating they are the equivalent to 40 or 60 watt incandescent are still a little offputting.
