Dexcool vs Old Reliable Green: Fluid Swap? 00-06 5.3

[Sweet 72]

I'm considering a complete flush of my cooling system on my 2003 suburban. It has 109,000 miles on the original 5.3 ltr engine. What I am curious about is if anyone has flushed their system and replaced it with the green? I am aware that once you add green to the cooling system there is no reversing it back to dexcool, from what I have been told. I've heard that the dexcool has taken out gaskets prematurely and that would be the main reason for the fluid swap. Has anyone done it? Any pros or cons on the fluid swap? I am planning on keeping the rig for a while and do not want to cause greater heartache.
Thanks in advance to all replies.
