She's basically AUG, but without the random fire mechanic. Which makes sense because she has an AUG. This logic doesn't work for any of the other girls, but shush.

If you'd like an evaluation of AUG to get an idea of how good Angelica is, here's AUG's article.

She has a very weird and complicated set of skill interactions for a role that really just wants good, consistent dakka. Has a funny combo skill with M82 (the bullpup AR, not the RF). In terms of performance she's actually not awful, but she doesn't stand out, and there are enough good ARs to use other than her.

Meet Milo, Miley's (AK-12) tomboy sister, who has literally no chill (you'll see why as soon as you meet her in story).

She is literally the most RNG-based DEFY member, with a chance to deal extra damage. If you'e lucky, she does good damage from the get-go. If you're super lucky, she keeps activating it while her active is going and you annihilate everything.

Because of how her active works, she's not as good at dealing with trash mobs, which can literally cut down her DPS. Be careful when using her, basically. She's REALLY RNG-dependent though.

Also, Abs. Did I mention abs? Yeah. Abs.

Ok, so she isn't actually bad. She does, however, have a stupidly long skill like a JK cramming for an entrance exam, most of which is largely irrelevant because all you care about is her damage output.

Which I guess is kind of alright.

Her skill has a good initial cooldown, and she's actually better than most ARs, but she won't usurp the position of the top ARs. A good pick for your B-team.

Can she dethrone AS Val's ridiculously solidified position as a top-tier damage dealer? ...Not really. She suffers from wanting some base crit rate, but making use of her crit rate requires either targets with shit evasion to begin with, a ridiculously high hit rate modifier somehow, or some other means of hitting targets at night. She might have some uses, but she's harder to use than AS Val, and you don't get much in exchange for it.

Basically what you'd expect from something that's the standard of the Mexican Army. Frankly, at this point there's so many good ARs that another one would have to be REALLY good to get a real recommendation, and this one isn't going to win any medals, but she has good uptime and is cheap.

Finally adjusted so she can stop being perpetually narcoleptic (sort of) through the power of energy drinks. She was already a decent AR whose weakness was that she couldn't hurt armor. Well, they solved the armor problem by doing percentage-based damage. Her damage is still affected by armor, but often she'll just do enough damage that you won't care anyway and can contribute to the fight regardless. She still has the issue of the poor uptime due to her long skill cooldown, but you should be smart enough to deal with that.
