Definitely 550. Better fretwork, better neck construction and finish, much better trem. The only weak point in the 550 is the pickups, but that you can swap out. The sustainer is cool, but I wouldn't bother with one unless you're sure you'll use it

 

+1 on the 550

 

thnx guys..hey Phishphood42 have u played with Jackson dinky's before.how does it feels like? is it the same as an RG?.. and guys.. for the 550 with neck finish would you prefer? maple or rosewood?

 

I owned a dinky reverse before, it feels good, neck is thinner than wizard, but they have a crappy tremolo compared to Ibanez's edge pro or Lo-Pro, Now i own an ibanez rg2550ex. And i will go Rosewood all the way.

 

Another vote for the RG here.

 

+1 RG

 

Whatever one feels best to you...

 

I own both a Jackson DKMGT, and an RG520, and have owned several prestige Ibanez guitars in the recent past and I'll say that I'll never sell my Jackson. The fret work and attention to detail on the Japanese Jacksons is second to none. I say that I've owned several Prestige guitars in the past because every one of them had some sort of significant flaw. My last two Jacksons have been immaculate, and my current DK is my main go-to guitar. I've got it loaded with a Dimarzio Evolution in the bridge and a Humbucker from Hell in the neck and it's absolutely sweet. My RG520 absolutely kills anything I've seen come out from Ibanez in the last several years, so if you can't get one from Rich, or a nice used one that's 8+ years old, I'd get the Jackson.

Of course, these days I'm playing my Les Paul an awful lot, so anything I say is suspect.

 

If you havnt bought anything yet, i say get the Jackson. I just bought one myself, its f**** great man. Anyway, you should know better than to ask an IBANEZ forum if you should get an Ibanez or Jackson lol.

 

Fairness and impartiality here, speaking from experience:

It all boils down to the sustainer. Basically put, the DK2S is an inferior guitar without it, though the neck profile is beautiful on those things. If you're gonna use a lot of the sustainer take that, otherwise go with the RG because it is definitely the better axe build-wise.

One other thing, you could actually save a few bucks if you go for the DK2S.

Enjoy whatever you go for

Edit: Forgot to mention, the Jackson has a slightly thicker neck, but not by much.
