My personal opinion on this is that as long as the tire is designed for the bike it is put on. Size, tread pattern, bias/radial, weight and speed ratings, then you are good to go.
The important part is knowing when to change out that tire. Inspecting it for microcracks, uneven wear, bulges, etc. It is the folks that run a tire until it NEEDS to be changed that increase their risk of a problem. And that is regardless of the namebrand and cost of the tire.
I had expensive Metzler ME880s on a bike and upon inspection found that I was getting cracks in the rain grooves. The tire rep warranteed me a new tire so I was OK. I've read of others chunking tire during a trip because they weren't inspecting.
So, you can buy the most expensive, or buy the cheapest. It is up to you to make sure they will perform for you through proper inflation and inspection.
