Track lighting is easier to install and adjust than recessed lighting. In any case, teasing wires up to the ceiling can be quite a chore, even for professional electricians. One approach is to have an electrician bring out a service for a hanging light in the ceiling. Then you extend that with a track light bar which is not too difficult for those adept at not falling off ladders.
There is a tendency to install both recessed and track lighting systems too close to the wall. Before installing anything, hang a test frame on the wall. With the help of a broomstick mounted spotlight held close to the ceiling, try various distances paying due attention to reflections, shadows cast by the frame, and so on. Take notes.
Right now I am very much liking so-called "High CRI" led spotlights which run very cool, emit almost zero UV, and cost a ton of money. The ones with CRI's in the 90's are quite nice, provided the color temperature is 3000K or more. Here's what I use in my art fair booth, and more recently in my print evaluation torture chamber:

Cree also makes some nice, high CRI leds. Just promise me you will not select a cloyingly Yellow 2700K bulb, yuck! Those things are suitable only for making the bananas look better at the supermarket, or for people who like the yellow jaundice look.
You can also find CFL's with relatively high CRI's, particularly in the 5000k variety. Seems like it's easier to get high CRI's in the 5000K+ range. A 5000K CFL can look pretty nice provided its CRI is up there in the 90's. However, if it exhibits the obvious High-Eye-Fatigue-Blue color of the cheap-is-good crud from Lowes and Home Depot, you can be sure that accurate color rendering is not its forte. But a 5000K CFL with a CRI above 90 will look fairly neutral.
Anyway, spend a Saturday at the art galleries and see what they're doing, lightwise. Spotted art sure looks nice, especially if it's yours. But for home use you might not want to emphasize the art as much as in a gallery. Or maybe you do. But nothing helps like perspective.
And I personally dislike the all-too-common MR16, low voltage fixtures because they use transformers which add needless weight and complexity to a system that can be so much simpler and more reliable if run directly on AC. And sometimes those dinky little overworked transformers catch on fire, just ask a gallery owner.
