I think you're talking about GE Reveal bulbs. It's pretty much personal preference-- no set positive or negative per se. GE's Reveal bulbs supposedly put out a light that closer to natural daylight, but when I tried a few I didn't much care for it--- seemed to make everything have a purple hue. Then again I know some people who love them. Get a few different bulbs and give it a try. In addition to standard Soft-White bulbs, Soft-Pink bulbs are an option; I have a friend who loves these. I remember back in the 80's these seemed really popular.

From an energy saving standpoint, I'd consider using compact-fluorescent bulbs. They are available in the flood-type bulb to use in your recessed cans. Personally, this is what I would do if the lights are going to be on for extended periods of time.

You can get full spectrum (or at least very close to it) bulbs in a variety of CFL and other fluorescent fixtures.
