I haven't had a significant issue with any CFL's. The only one in my house that gives problems is the one under a set of stairs, that is upside down, and never used. But even it comes up to full brightness after a bit, the few times I've turned it on. I do have some regular tube fluorescents that give me some issues, but I don't know their age, or the condition of the fixtures, so I haven't bothered with them. They will come on just fine with some prodding, so it's not been a major issue. One day I'll have to see about changing them out, they're a bit mismatched in colors, so it is slightly annoying.
I haven't tried any LED bulbs yet*
, I want to get some to replace the dead flood lights on the corner of my house, as they are a good 30 feet up, so I want to avoid changing them as much as possible. But I don't have a ladder to reach them, so why purchase the bulbs? Not like I don't have plenty of other lights, including a huge sodium light in the backyard. I have no idea how efficient it is, or how much wattage it uses, but it puts out a lot of light when it's on.
In regards your outdoor lights, it might be a problem with temperature and moisture, there are some CFL's designed to stand that better than others. Mine don't have an issue, but I couldn't tell you if they're special or not, they came with the house. And the GE CFL's I have are much more on the Yellow end than other bulbs, so I can recommend them for those who prefer that color. Haven't tried the new CFL Reveals though. I did like the incandescent ones, but I haven't had to change enough of my bulbs to warrant buying that many new lights.
Also, don't complain about having a single four post fixture, I have a room that size with NO overhead lighting at all. All it has it a post-lamp on the stairs. I'm not entirely surprised considering the age of the house, but when I factor in all the other renovations, I'm baffled.
