Difference in Bebop sets

[Terrex]

Recently, my neice ruined my Cowboy Bebop Set (The AV *or is it VA?* set). I'll probably buy a replacement set, so here's my question. I know FX has got the best import sets, but I see that they both have the same rating in the reviews. I've heard the AV set's are ripped from the FX sets, but I'm not sure. Should I stick with AV/VA set (a local store sells them for a pretty good price) or should I order a copy of the FX set?

Any help would be much appreciated.
