While I believe in speaking within the framework of your experience and knowledge, I also know newbies asking questions like this regarding equipment recommendations aren't looking for a lot of self-doubting equivocation:
He then asked me "What's the best compass out there?"
I think it's implied that it's in the instructor's experience that the answer will be derived, that the instructor is a fallible human who may make mistakes and hasn't tried all models of all brands for lengthy durations for a variety of usages and techniques, and thus can't speak from first hand knowledge to give a single answer for everyone.
But the newbie didn't ask for an extended exposition. He assumed the instructor had enough experience and awareness of some name brands, and that his recommendation as to the 'best,' with the questioner in mind as a presumably mainstream OW recreational diver, would produce a good quality product (though in the fullness of time it might not be the absolute best possible option out there).
This is especially true of some products, like compasses.
There are some products, like regulators, where there are a range of quality brands & models that are very comparable with some price variation, some such as dive computers where capabilities and interfaces vary widely (e.g.: tech. nor not, console vs. wrist, AI or not), and some such as fin types where application is key and individual preference often conflicts (witness the split fins debates, and the issue of whether you'll be frog kicking in them, etc...).
For those products, answers for Atomic Aquatics 'Smoke of the Water' split fins, Cobalt dive computer and B2 regulator, best bang for the buck, yessir, would be over-the-top if not at least qualified a bit with why & for what you consider them 'great' for.
But I think the Suunto SK7 (I've got some myself) was a fine recommendation, wouldn't have steered the newbie wrong, and wasn't indicative of an image conscious pro. trying to look good and impress the newbie.
If the newbie really wants some multi-party perspective input, have him read a bunch of our split fin debate threads. After 20 pages or so, he may be ready for someone to say 'Buy this one!'
