In general, the Domination and the Terminator are 2 different balls with 2 very different ball reactions, intended for 2 different oil amounts.
One would not, in general, consider them to perform the same task.
The Domination is a resin pearl, with an extreme skid/snap reaction intended, in general, for medium oil, at its strongest. It can handle lighter oil.
The Terminator is a solid particle, with 2 different sized particle (not Diamond, as far as I know) and intended for medium-heavy oil with slightly more length (SLIGHTLY!) than average and a strong read of the mid lane. It can probably be used for slightly less than medium-heavy oil, but unless you have high ball speed or low revs, not really useful on medium oil.
If the Terminator were sanded, it might be the strongest oiler that L/LM has. (MIGHT!)
