Which sprinkler heads are better, rainbird,hunter or toro?

I worked at an irrigation warehouse for 8+ yrs and sold to 1000's of different contracors. Hunter is by far the most used & the quality is good, rainbird comes in a far second (it's also good but hunters just a better known brand name) we carried toro for a while the s600 & s700 series but they never got bought. I guess it depend on the application, if it's for residential use or you need something large for lets say a soccor feild etc..either way i'd say hunter then rainbird as they are most common & easier to find replacements for. Also check into K-Rain RPS rotary, it has the same patent number as the Hunter PGP series & the person who created it, I think, even worked for Hunter at one point.
