I just have the cheap trustfire charger. Been using it for years with no problems. I figured I could get 3 more batteries with it instead of the pila. No regrets.
I want the best charger and batteries that I can find. No reason to skimp on them since they are so important for my APV's to function efficiently. Just think how many times a day you use press that power button. Not only is battery duration important, but so is safety and the total life expectancy of the battery. The recharging algorhythms used by the Pila and Xtar chargers are unique compared to the off brands. They just might prolong the expected lifetime of my batteries.
No regrets here using only the Pila charger and genuine brand AW batteries.
I don't trust any battery any longer that has the name "trust" in it, as I had a Trustfire "protected" battery go into thermal runaway when it shorted in my mechanical mod.
