I have one Gibson ('76 LPC), three ObGs (57 Cst RI, 57 GT RI and one non-RI lemondrop), an Edwards (Sykes-ish model) and a japanese Epiphone (LPC90 - like a 57 RI, made by FujiGen, who also made Orvilles, Orville by Gibson and now FGN).
The "better" Tokais and ObGs are easily comparable with what the Gibson Custom (!) Shop is building nowadays, while the normal FujiGen and ESP-Edwards stuff is comparable to the average Gibson.
When buying a new Edwards you will be surprised that the craftsmanship is even better than standard Gibson quality. The pickups used are different though, Duncans normally . . .
I have no experience with Grecos and Burnys (Fernandes) except playing some of them here and there. The Greco Super-Real LPs are awesome (and very expensive), in the same range as the higher Tokai models. Burnys (their customs have no ebony board) are cool too, but not on the high level of ObG and Tokai >100.
Super cool IMO are those japanese Epiphones (same headstock as Gibsons), they are super well made and because of their branding not as expensive as the other brands. Esp. LPC90 and LPS 90 are awesome and you can get them for 700-800 Dollars, but they are super rare in europe and the US and very hard to find even in Japan.
