Need help apraising these TFs I just got off ebay

I recently bought a few things off ebay
RID Scourge (japanese version with US version stickers for some reason)
Reissue Prowl
Hybrid 01 Galaxy Convoy (just about one of the craziest TFs I know about, get one now if you don't already)
Reissue Soundwave with Rumble, Frenzy, Ravage, and Laserbeak
But I have a few questions about them because they came loose and complete.
Prowl's missles and gun are black plastic and not chrome, also the launchers don't shoot (I think),
I assume this is just how the US reissue looks like but I'm just making sure.
I had previously bought a frenzy (blue one
) at the Toronto transformer con (for 5 bucks) comparing it to the one I just received I assume one is a knock off (perhaps the rumble I just got too)
My old frenzy has a rubsign on his back, nicer looking chrome on his weapons, darker blue on the stickers on his arms, and his stickers are more metallic looking than the new one. and came missing one sticker on his arm and missing one foot.
The new frenzy has a different face shape, no rubsign, a plain non rubbing decepticon sticker on his front, lighter blue on striped on the stickers on his arms, though his stickers are still metallic the details on them are not and the black lines on them are thinner.
They both have metal feet and gear things.
I hope I described them correctly, I am not near them at the moment.
I will try and post pics later.
