Mmmmmmm....

....depends whether your talking of a spinning or conventional/baitcaster (eggbeater or overhead in Aussie speak, spinner or multiplyer in UK/Euro).
I wouldn't put anything I've seen above the Diawa Saltiga Z spinner range, but if I was going for a conventional I would first check-out the Blue Heaven from Studio Ocean in japan (cus everyone who's seen/used one raves about this reel).
After this I would check out the Tiburon range simply because of the superb standard of their workmanship on a 4/0 Penn body I had from them when they first started up, its still rock solid after 20+ years of heavy hauling from 300+feet, I cannot fault it!
Maybe you should also consider what type of line your gonna use?
All japanese jigging reels (and rods) are designed for Spectra braid, PE in jigging speak. The spool standard of measure is 300 metres and if filled correctly this IS what they take, no guesswork or backfilling required.
Check japanese shop sites and for interest their jig rod manufactures are worth a look. These feature rods under load, with specific rod angles and reel drag settings. If you've never seen them some are really mindblowing!!
Many feature reels on the rods and these will give you more ideas to work on.
Hope this is of assistance.
