The FR is the same but only where they are made has a difference. The production process and materials used are 100% the same.
The fretboard is of excellent quality, how did you come up with that one?
RR3 would be the mid-class Jackson and that isn't shit. The fact that you can afford a expensive ESP doesn't mean my guitar sucks, or for that matter a lot of the guitars.
JS30RR are quite bad (but ok for the price), RX10D suck for the price, RR3 is very good for the price aswell as the RR24. The RR1 is too expensive for what you get.
If the RR24 is better or the Alexi-600 isn't purely based on specs which are almost the same, it is 95% based on personal preference plus IMO the USA RR shape sucks in looks (but has excellent playability like the original RR does).
What you are doing feels to me like 'I have an ESP and anything else isn't quite as good'. I'm not saying you're behaving like this, I'm saying I feel like you do. This is not hatred to you because I like you as a guitarplayer and you're a pretty cool guy aswell but this whole rant of you that Jacksons suck just doesn't make ANY sence.
