most of the times, damage that is given from created environment like that (sns, nilbog, eloia's bow proc, etc) is not based on your pet level, but the 'level' of the map you're in,
so you can consider titan's aa damage is maxed already, while mm's aa most probably can go higher by its level,

so yes, until both are capped/same as your level, we can't make any clear judgement
