Fighter/Mage/Thief vs Mage/Thief (for full BGEE/BG2EE playthrough)

So, I've got my cleric/mage, sorcerer, wild mage ready for BG2EE playthroughs, and I'm trying to decide between f/m/t and m/t for my next playthrough. I'm having trouble discerning what the fighter part of the multiclass brings over the m/t version.

f/m/t brings:
- better thac0
- more proficiency points
- better hitpoints
- I am pretty sure it gets extra attacks per round, but I'm not sure on the exact details, anyone care to fill me in please?

f/m/t loses:
- mage HLAs, even if xp cap is removed (though I have found a mod that "fixes" this within the framework of what the engine allows).

m/t brings:
- full mage HLAs
- more mage spell slots
- faster progression

m/t loses:
- fighter HLAs
- the other fighter bonuses already mentioned (hp, thac0 etc)

In most discussions I've seen about things like this, people mention using tensers to get the fighter thac0 when you want it etc.. but I'd prefer to leave that possibility out of the discussion (I'd be using the spell slots for other spells normally etc).

I'm not considering the dual class thief -> mage etc, because I'd like to get some of the thief HLAs eventually (Use any item springs to mind for this concept).

Thanks for any advice!
