I had a time years ago when I was hugely into the PowerLock and PowerPlier. One nice thing I can say about it is the individual tools are fun to swap out and custom configure to your own liking.
I can honestly say I got a lot of use and enjoyment out of my PL. Although I did snap the plier head off while bending a piece of metal, I sometimes regret selling off my SOG collection. The knife blades although chisel ground were nice and replaceable, the V-cutters were cool and they cut great. The drivers were good. Pretty much everything but the scissors worked adequately.
So, if you enjoy yours, I think that's a good thing. Take my advise though and try to accumulate as many extra pieces and parts as you can. This includes extra knife blades, drivers, cutters, etc.
I'd like to see pics of your PL's if possible
