I've been using CFLs for maybe 20 years now. Originally they were very expensive
(up to £15) and I only had a few in locations that were illuminated the most.
Of course the price dropped over the years and 'green discounted' CFLs (Philips
brand too !) can be bought at the local supermarket for a mere 39 pence (75
cents US) right now. I only have 2 incandescents left.
I'm pleased to say I have had ZERO early failures. The more expensive ones did
tend to last rather longer for sure though. Various brands and models have had
lifetime ratings of 6000 through to 15,000 hours and I have no reason to doubt
those figures.

Almost all of mine have been Philips or Osram.

On average in my home, I might lose one CFL a year. Before, I was changing
at least one incandescent per month. I suspect that the electronics in CFLs may
be more sensitive to surges than incandescents. That may explain the bad luck
that some seem to have with CFLs.
The two 12 volt CFLs that I use for outside lighting are (I believe) about 6
years old now with no failures.
