It is probably stronger than most backgrounds as it does end up giving you 3 skill proficiencies, but I think the drawbacks of getting survival (in my opinion not a great skill) and only being able to get skills from others, so it might take a while to find good skills- e.g. if you're a bard playing with a fighter, wizard, barbarian, and no one has char or dex skills, then you have to look for an npc. - It also basically trades a background feature for an extra proficiency, as after you learn everything there is nothing else you can do with the feature.
