Which one of those is actually worth making?
Does the magian weapon of choice change depending on whether you use hexa or realmrazer?
How badly needed is the tp bonus club for extra acc on realmrazer if you are actually bothering to melee on geo?
Str magian looks like a joke option compared to lv99 Ukaldi w/ 10% ws damage + 16 more base damage.
This is speaking from the perspective of a WHM, who shares a similar skill level.
You don't really need ACC on anything as a WHM, so I imagine it would be a similar story on GEO. I pop Pizza while in SoA zones, and if you truly need ACC, you might as well run with a DEX off hand to help boost that accuracy number slightly. Anything else that isn't a level 120 mob, GEO shouldn't have too many issues with it (I crack 95% Accuracy and no ACC food on Qilin, but that's VW, I haven't tried to fight anything similar outside of VW).
TP Bonus Club is nice, but given the delay factor, the differences between that and a STR club aren't as pronounced. Your WS numbers will suffer slightly because of the damage difference but on a 100% modded WS it won't be as bad since the majority of your D rating will come from your gear at that point in time. It may make more sense to use a TP Bonus Club in Abyssea while spamming Hexa Strike as the additional Crit can be beneficial.
I personally would build PDT, STR, and DEX as they all have applications. PDT + Genbu's for front line support and helping out with the PDT category. STR is just a general nice off hand (especially since GEO can't use KClub if you happen to own one) and DEX has niche uses, especially in current SoA areas.
Just bear in mind that building for GEO melee will be more difficult than building for WHM melee as WHM has a few pieces of specialized gear that excels in this category. Though given GEO has access to certain pieces of gear related to nuking classes, that might balance out in their regard (Staff for Shattersoul / Cataclysm comes to mind)
