My post you quoted does not mention CFL bulbs. They do however, last longer than incandescents, the exact amount depends on how much you use them, and your useage pattern. LEDs don't have the same problems as CFLs with premature burning out, as usually it is the ballasts in CFLs that go. LEDs do not have ballasts, or even capacitors, as you say.
I don't know where you are getting that LED bulbs do not have an instantaneous on time. In reality, LED bulbs come on faster than even incandescents do.
Again, LED bulbs don't have capacitors. At the very least, they are far more reliable than CFLs, and certainly even more reliable than incandescents. They are also significantly more durable than CFLs and incandescents. Try dropping a CFL or a incandescent on the floor and trying to see if they still work.
The limited view angle can be an issue, but many LED bulbs throw light in most directions. You can get LED bulbs for different applications. In many fixtures, the light thrown backwards by a CFL or incandescent is nothing more than wasted light (i.e. pot lights and track lighting). Even in lamps, it not really a big deal, other than the lamp shade looking a little different.
