Mage companion dilemma

[Metathron]

I'm a level 17 mage on normal and I've been planning all along to recruit Elenhel for the +4 intellect bonus as soon as I reached intellect level 20. However, I have just now found the potion for my current companion, Jim Crowd, that makes him beautiful again, which gives me another +700 leadership.

So now I'm in a bit of a dilemma - is 700 leadership worth losing for 4 intellect? Also, the different slots make me sorta reluctant to switch because I don't know how much I'll like Elenhel's slots (no weapon, bleh). Not saying I have good items equipped atm (actually, mediocre at best) just that I like to stick to companions for as long as possible.
