"Second gens trigger easier" is an in-universe misconception, born of the fact that second gen triggers are simply more likely to have a shard watching them. There being more consistency makes it seem like things are easier, makes them stand out, but it's not actually easier for the person triggering.
As well, Glory Girl's trigger being presented as getting off easy is done by Lisa, at a time where she has a vested interest in making heroes look as bad and dirty as possible to the wannabe undercover girl, and we know she lies or makes mistakes of that sort, because she does it again when subtly telling Taylor to go for Brian, who immediately shuts Taylor down and doesn't consider her again until literal life-changing and life-breaking trauma.
From outside context, Victoria's trigger IS easier than any 1st gen trigger we get told about.
in comparison, without internal thoughts of the person triggering, Vicktoria's trigger appears as shallow (getting fauled in an important game) when in contrast to:
1. being emotionally abused and harassed for 1.5 years and then being shoved into a locker full of disgusting things.
2. your brother commiting suicide.
3. walking in on your mother's newest bf abusing/harassing your baby sister.
4. having your puppy drowned in front of you.
Those are all first gen triggers that Lisa is aware of at the time (bc iirc Brian talked about his sometime early after Taylor joined).
Even WITH Victoria's actual worries, insecurities, and realization that were her true trigger (failing expectations, being ignored during her most important moment, etc) - when compared to most other first Gen triggers, it seems less.....intense. Less despairing.
Especially if you include the things that were going through THEIR minds at the time (being abandoned by everyone for Taylor thinking that nobody cared if she dies, failure to notice her brother's failing mental health and being blamed for it, failure to protect his sister, etc).
