This is why I wrote that it indicates "on what dimensions it's supposed to excel". Here's a non-abstract example:

----

Mercedes CLS550: the safe luxury car.

BMW M5: the sporty luxury sedan.

Toyota Camry: the reliable family car.

Hyundai Sonata: inexpensive, practical transportation.

Jeep Wrangler: fun off-road vehicle.

----

Nobody is going to refer to their car as unsafe, not sporty, unreliable, impractical, or not fun, but that doesn't make the brief descriptions unhelpful. It tells me why the creator thinks their car is different than the others.

And while nobody will say "the slow, difficult way", they might well say "the most powerful way", "the fully-customizable way" or "the environmentally responsible way" all of which indicate to me that they are differentiated by something other than speed or ease of use.

Your proposed alternatives tell me absolutely nothing except what market the product is in. You're making me work to discover why your product is different than others in the market, and that can't be a good thing for you.
