Well, this is pretty obvious. I'd choose T&T. Here's why-
T&T either trumps or can be used as equally effective as the following-
Geomancy- T&T can also cause the earth to shape-shift into objects that appear to be golems. Furthermore, controlling plants at the molecular level can cause rapid growth, just like Geomancy.
Hemomancy - T&T can virtually destroy hemomancers by controlling their minds and making them no longer crave blood. Furthermore, T&T can control blood on a molecular level, and can therefore drain all the blood out of a hemomancer himself.
Necromancy - This is pretty easy. A T&T can control dead things just as easily as a necromancer. While the dead things wouldn't be "alive" like a real necromancer, a T&T can still achieve the same effect. A T&T could also control the same dead things that the necromancer is controlling, thereby making the necromancer ineffective.
Water - A T&T can control water on a molecular level just as easily as a water seer.
Fire - Same as a water seer. Controlling fire on a molecular level would allow a T&T to either ravage cities or to prevent a Fire seer from ravaging cities. Your choice.
Lightning - Same as water and fire seers. Control lightning on a molecular level.
Arcane - Since arcane is a magical property and not necessarily a physical property, this one would be a bit difficult to control. However, by merely inhabiting the mind of an Arcane Seer, the T&T could control whatever arcane powers the Arcane seer possessed.
Time - This one is a bit tough, but here goes. By entering the mind of a Time seer, the T&T can prevent or force a Time seer to do certain things. The T&T can travel or freeze time simply by entering the mind of a Time seer. Granted, if the T&T were to freeze time through a Time seer, the T&T would also freeze. However, the T&T's ability of mind control would still work even though this his physical body were frozen, thus allowing him to still accomplish his goals through mind control of the Time seer. Furthermore, the T&T, through being able to control things at the molecular level, could force his own frozen body to move however he'd like while time was frozen.
Future Sight - T&T doesn't really need to fight a future. A future seems quite harmless. However, a T&T could enter the mind of a Future and thereby also see the future, providing the T&T with the powers that a Future holds.
Holy - As long as a T&T mage isn't evil, he'll have no qualms with a Holy. Otherwise, an evil T&T may be in for a very tough fight against a Holy, since a Holy doesn't work on a molecular level, but rather a spiritual level
So there you have it, T&T by far the superior force.
