Oh, there are
plenty that are underwhelming. Emerald City and Power Plays are full of those. Stuff like "Gain edge when interacting with NPC faction" or "Gain Edge when making a specific test in a specific geographic area". I don't mind seeing these, because they're harmless chaff. They can't all be winners

Regarding Catlike, Guts, Toughness, and Gearhead: I don't have the 5e CRB in front of me, but the cost difference there might be copypasta. Copypasta is
SURELY to blame for the Analytical Mind garbage, it was 3pts in 5e and only applied to puzzle solving, hence why it's 3pts in 6e. And the authors seem to have come to an agreement that 12 pts is too expensive for situational, temporary edge qualities. They just wouldn't revise the cost of old qualities for some reason, instead they rebalanced similar new ones and spent a bunch more ink coming up with optional rules and home made quality examples.
The cheese of Limited Attributes/skills doesn't begin to compare with the cheese of Impaired Attribute : Strength, or Incompetent: Cracking. I think Limited attr/skill are actually well made qualities, because maxing out your primary attr/skill is a formula for success in SR's linear cost chargen. You really are hampering your character (imo) if you don't choose to do that, so why shouldn't you get a free specialization (5 karma) or other perk for doing so? Well I say free, but you do have to spend 1 of your 6 possible qualities on it. Ever since Street Wyrd packaged a lot of Tradition-specific differences into Qualities, I've started weighing opportunity cost when picking them. Like, if you want to play a possession animist with a totem, you're probably taking 3 qualities right there.
All these Companion qualities haven't been around long enough for people to kick the tires on them yet.. lessee here. Tracker doesn't bother me much since Tracking is such a niche skill, but you're right that by their own guide in the Quality creation section, it should be a 10 pt quality. Tracking's use probably varies a lot between GMs, but I can see a Tracking test being done as an extended test, in which case Tracker would only trigger one time for the whole encounter.
I actually
love] Motor Pool at all levels - just not with a Rigger. The Influence + Charisma (4) test makes it too risky for anyone but a Face. For a Face though, this ability is a great way to roleplay someone well connected, like a Fixer. Motor Pool 1 is pretty meh, granted, this type of transportation is typically handwaved and the cost is assumed to be covered by lifestyle if you're not nickel and diming your players. But if you allow it to be used for other people and NPCs, it can improve the utility.
My personal favorite quality combination right now is Bad Luck and Silver Lining. I like seeing glitches during a session, and silver lining takes a little bit of the sting away if it happens often.
