Well, most of the gear you're talking about is made by 3 companies. To avoid the standard Good-Bad-Better-Best quality mechanic, you could use the three companies to rate gear, namely Militech and two other Asian companies (can't remember their names). So, if this feature would be implemented into the game, then your quality can be based off of which company it comes out of.
I can understand that, but even when discussing a single company. there is a product range of different things.
Some products are designed to be cheap and basic, others have unnecessary features like curved displays and so on to attract the people with more money than braincells (what I want to roleplay).
A company is foolish to make stuff that is only high-end, or only cheap stuff, they make a diverse range of products that fulfill the same basic function(s).
