Use whatever your car already has in it.
I use ethylene glycol, (the green stuff) which is what it has always had.
I suspect your car has the orange Dex-Cool. Keep using that. Even if you flush, using the same stuff as before gives you peace of mind that the different coolants won't react and become a viscous sludge that blocks your cooling system. It's less likely that this will happen after a good flush, but you never know if there's any left in the system.
Either work well and neither really is better than the other.

I've had no problems with DexCool in either of the two previous Lexus SUVs we had that used it. Just ensure that whatever fluid you choose meets the required specs before you pour it down the hatch. Coolant gelling caused by mixing various flavors is indeed a major issue that can eventually kill your engine....
