That says something to me!
If Yonny had some bad ones from Monster, and yours 'aren't right', a bit vinegary, (even if delivery was delayed) personally I would avoid Monster Particles.
When it comes to ready prepared particles, those in the containers by Dynamite, I have found to be the best, as they are actually cooked in the container I believe.
As Yonny says, preparing your own gets best results and you know what they are like. I normally do all my own particles, I can experiment with soaks and solutions, but to be honest, in most cases particles are most attractive and need no extras than soak and boil/simmer. Adding chilli, garlic or whatever rarely makes them any better than the standard.
Tigers are a soak for 24hour minimum, and then boil for around 30mins.
