The best consumer goods are generally the ones where the design has persisted unmodified for decades. It works, everyone uses it, nobody's improved on it, serviceability is reasonable relative to the essential complexity, and it hasn't been cost-reduced into garbage. "New model" always comes with the worry: What did they fuck up this time?

Anything "professional", "military", etc. comes with the potential downside of it being someone's job to maintain and service it. Qualitative differences usually come with trade-offs - and if it's not your job, it might not be better to try.
