One of the things that's always bugged me about D&D and d20 games is the laundry list of weapons and armor. Some people really like them, I get that, but the way the lists are designed, there's clearly a "right" choice for each. The longsword with it's top dog damage and proficiency bonus in 4E, and plate + shield with it's top AC bonus and minor drawbacks.
I partially agree with you, in that I think there should be good choices for light, heavy and maybe medium armor. And, similarly, there should be several good weapons for PCs to choose. But I disagree with the assertion that 2nd rate weapons and armors are bad for the game. They serve two useful purposes.
First, bad weapons and armor give the PCs someone to shoot for in the early levels without having to find magic weapons and armor. Forcing the fighter to start with split allows equipment advancement into plate and full plate without having to provide +1 magic armor at 2nd level. Not everyone like counting copper pieces, but it's an important part of certain styles of low-level play.
Second, bad weapons and armor are useful indicators for NPCs. PCs can react to an orc in plate armor differently than an orc in hide or ratty chain. Similarly, it allows DMs to give crappy equipment to NPCs without worrying that the PCs will cart it back to town for an inadvertent humongous payday.
