Re: MMS vs. Hydrogen Peroxide
As I have pointed out in previous posts the real reason chlorine dioxide is used over chlorine is because chlorine dioxide is 10 times more soluble in water than chlorine gas, and is a more effective oxidizer.
Here is a list I found of other advantages:
Strictly as a disinfectant, ClO2 offers the following advantages:
• Its bactericidal potential is relatively independent of the pH at between 4 and 10.
• It works better than chlorine for treating spores.
• It needs little contact time.
• It is quite soluble.
• No corrosion is produced at high concentrations, thus reducing maintenance costs.
• It does not react to ammonia or ammonium salts.
• It improves coagulation.
• It is better than chlorine for removing iron and manganese.
As I have also pointed out in previous posts, chlorine dioxide is not very stable and DOES NOT remain as chlorine dioxide when reacted on by other things such as sunlight or water:

And as far as your claim that chlorine dioxide does not create trihalomethanes (THMs), this is not quite true. Chlorine dioxide DOES create THMs, just to a lesser extent than chlorine.
There is a chart on the THM formation by chlorine dioxide showing lower production of THMs, but production none the less:

Some studies on THMs including toxicity an side effects:
