Wera screwdrivers differences?

[SoulDe]

I want to buy a good set of screwdrivers to replace my screwdrivers Stanley. Wera was watching the brand. I was looking on Amazon, and found a few sets at a good price.

What is the difference between these three models, and what should I buy?

The stainless is only good for working with stainless hardware. That would be my last addition...

The Lasertip is a all around general driver set. My first choice...

The Chiseldrivers are good for more abuse. Prying, hammers, and other misuse. First choice if you are hard on screwdrivers. Although I prefer just to keep some old Craftsman screwdrivers around for that...

Stainless Steel Wera drivers are for sensitive industries, such as food industry, Nasa... : No rust tips, always clean. Generaly speaking, stainless steel tools are more fragile and have a limited torque. They're not destinated for a general use as mechanic or houseworks, so...forget them.
Others Wera's, those with a Green handle and "lasertips" are perfect for a general use. The Yellow handles are similar to the previous but with a shaft running trough the handle and a striking cap. They're also known as "chiseldrivers".

Thanks. I'll buy Wera Kraftform Plus – Series 300 for routine works that does not require using the screwdriver as a chisel.
