I don't fully understand the Blind spot Vigilante Talent, I understand that it allows the character do a stealth check against a creature that normally spot you, but that creature gain a +20 bonus to see you if you don't use another ability that help you to hide (like the spells that mention in the book) am I correct or I just misinterpreted the text.

Normally those abilities auto detect you without even needing a skill check for perception against stealth. It's like trying to sneak up on Daredevil with his super senses. Can sneak with all the concealment/cover/stealth modifier you want, he knows you're there without needing a perception check.
Normally to get pass those special senses you'd use tactics to bypass the ability outright, such as the listed examples (negate aroma vs scent, flight vs tremorsense). Someone uses those, the target creature doesn't have those senses as an advantage anymore.
Someone not using those methods, and just have the Blind Spot talent, still has to deal with the super senses, but they at least have a chance where the creature still gets to roll (with a +20 bonus to perception because they still benefit from the sense somewhat) but the stealthy character gets to oppose it with a stealth roll. Kinda like in Netflix season two of Daredevil....
A stalker vigilante investing in Blind Spot would be smart to also pick up the Dampen Presense feat which would negate the +20 bonus of only having Blind Spot vs blindsight and blindsense.
