With the advent of her mod, she goes from being Thompson's kouhai to one of the strongest force shielders available. Too bad G36c mod exists now, but let's not talk about her.

Through the power of milk, when she lowers her force shield, she gains a decent evasion buff to turn her into a mixed force shield and evasion tank. While the buff requires there to be multiple enemy packs, any amount of evasion to go along with the force shield is welcomed. Oh, did I mention she also buffs rifles with her tiles now? That's a thing. The buffs she does provide aren't particularly useful for rifles, but it may come in handy.

She DOES require her unique equipment from the night map to function effectively, for the milk tin is all powerful. The mod equipment, however, is pretty garbage.

So if it hasn't been said enough, absolutely get the Mod1 the very second you can. It's 200 fragments and some cores for a fair boost in performance. Extra stats, a bit more FP buff on her tiles, a little extra HP, and an improvement to the slowdown effect on the smoke.

The real problem is her 2nd skill is janky and not extremely practical. It's a little bit of a bonus, but not likely to make or break a fight. So yeah, the Mod2 isn't great. The mod 3 however, gives her a unique equipment that goes in the suppressor slot and is basically a suppressor with better stats (+5 EVA over normal) which helps her tanking ability somewhat. Whether this is worth it up to you, but definitely get the Mod1 at least.

The rest of this is basically the same song and dance where she has top class offensive buffs that continue to remain unmatched among SMGs, so you WILL likely continue to use her.
