Your statement would be true if all cables were equal and a 75 ohm cable was a 75 ohm cable. Typically the higher price cables offer better materials in the manufacturing process and better workmanship in the assembly process. This is why they exist today. Your third paragraph helps to illustrate my point.
I like Monster, they make great stuff, but there are less expensive alternatives that are made just as well.
When it's all said and done though, what influences our decisions most will be cost. You just have to get out there and try it like he said.
