Toyota's current red coolant is an OAT (Organic Acid Technology, like DexCool), which like most Japanese coolants contains phosphates but no silicates.
It differs from DexCool primarily in that it lacks 2-EHA, which Toyota seems to believe creates some problems with gaskets.
From what I've seen the current Honda Coolant is about the same despite the color difference.
If you own only Toyotas their coolant makes a lot of sense.
Universal antifreezes, which are usually some version of a DexCool clone, often contain 2-EHA, which is something of a no-no.
In my own fleet, which includes a Toyota which came with the red fluid, a Hyundai, and an '06 Malibu I've settled on G-05, which is factory fill on Ford, Chrysler, Mercedes, and some others.
The slight trace of silicates doesn't seem to cause any problems in years of use, it avoids the low coolant problems that arise with DexCool and its clones, it's long life, and it's pretty much as close to a universal coolant I've been able to find.
