Cool, I wasn't aware they reissued the EXB series. Odd to rename it, but also understandable given its resemblance to the popular RG guitar range.
Can't go wrong with the SR300e, the Soundgear is Ibanez' "can all, do all" range. Any Ibanez will offer excellent value for money in its price range, so I bet the RGB will be an excellent bass too. Both have thin, flat necks so you might want to try them in person first. The pickup configuration in the EXB is very popular among metal bassists.
For death metal and the likes, you might want to consider going 5-string for the added low notes down to a low B. Since you specifically mention your long fingers, you might just enjoy the extra width too. Both models are available as 5-string, the RGB305 and SR305.
