I have always had cheap ST Chinese junk and never had a blowout but never trusted them, mainly be the way they rode and looked marginal at best for the load they were carrying. On my last fiver I upgraded from Ds to Es and went with Maxxis. They are a far superior tire in my opinion and didn't have a problem for 2 years up until I traded for my current fiver. I will say that a move from D to E is a wise choice as long as your wheels are rated for 80psi.
When I bought my new fiver last year, I had them put a set of Firestone Transforce LTs before I signed the papers. I didn't want the Road Riders junk ST Es that came with it. I have only had them for a year, but will say that I made a good choice. They look and ride like a real tire and I have the upmost confidence in them.
Everyone has tire opinions, just do what you are comfortable with.
