The Super Dooper Looper and Comet at Hersheypark have both provided relatives and friends of mine with infamous moments. My dad and brothers got stuck at the end of the Looper (my mom and I had sat it out after riding it once, but they couldn't stop riding it that day), and one of my classmates told me a story about throwing up after riding the Comet once.
I don't go on upside down rides.
Not sure that your opinion on roller coasters is well-founded, then.
The best ones don't go upside down. Ones over 200 feet usually don't have inversions. Loops are the Pennsylvania Turnpike of rides for me.
At this point, your experience is so limited that your opinion has no broad application.
A healthier perspective for you would be: "I really liked Fury 325 and look forward to riding more costers to see if the rankings are right. Someday, I'll start going upside-down..."
I mean, my son loved Gemini at Cedar Point and rode it a bunch of times (great coaster), but he's not so naive to say it's the absolute best one in the world, since he knows there are a ton he hasn't ridden.
