I have used it all and prefer the Platinum.It doesn't get brittle over time like super glue type glue.
It is also cheaper and doesn't dry out like others.You may have to clean the tip out from time to time but that is it.
You apparently are having a cleaning,or prep problem if it isn't sticking for you.
