I just mentioned how the Oscar is an outlier, also it does bloom a bit. Also, if you check my edit I corrected myself that the Logitech G403 has a good sensor and can scroll-wheel.
Now theoretically speaking...
If you were to go pro, you cannot scroll-wheel. Your brain needs to react and shoot, not think... "oh hurr durr should I scroll-wheel or left click?"
Conclusion
Scroll-wheeling works against noobs, or can help in cqc if you are primarily scroll-wheeling. For more serious gameplay it is a hindrance.
