Replacement lighting coils, which are better OEM or aftermarket?

[eBoyDog]

I'm going to replace my lighting coil on my ytm200ek, I keep getting weirdness fromit as sometimes it works and other times it doesn't, ohm meter gives flacky readings so im not sure if it's the wires or the coil it's self so im just going to replace it.

Which are better, the oem nos or the aftermarket replacements? I intend to replace the charging coil too while I have it apart? Is the higher cost of Yamaha NOS worth the extra expense or are the cheaper ones ok?
