Freelander 2 (LR2) ATF Choice for 2010 TD4

I'm swapping out the torque converter on my TD4 and I've been looking at 3309 ATF for when I come to fill up the box again. I can get:

10L Mobil 3309 for ~£75
10L Smith & Allen 3309 for £66
10L Westway 3309 for £64
10L Mannol 3309 for £39.94

Does anyone have a quick opinion on which I should get and why?

I use Mannol oils, finding them good quality at sensible prices. So as long as the Mannol says its the correct specification, then I'd go with that.
