The extra bonuses from ranks 2 and 3 of this perk also apply when not sneaking, so it may be worth it for even non-stealth characters to take levels of this perk.
All companions have the effects of 4 ranks of Sneak except Curie who is missing all ranks of Stealth in both forms (robot and synth). Dogmeat has a unique Stealth Rank 5.
