Momentum can be used for burst AoE, Nemesis can not. Nemesis only works on AoE when you kill an enemy with the same type as every other enemies.
With the 5% increase on Nemesis it will be more likely to use it somewhere, but there will be enough situtations where Momentum is better.
And you need a whole minute for it on a target or be able to kill this target to have the full uptime from it.
If Nemesis would be theoretically better, i would use it only on:
Nythendra (non mythic)
Ursoc (non mythic)
Cenarius (with burst tactic)
Guarm
