9E's bad one was 3701. No pax were killed because it was a repo flight. A year before that, Colgan had a 1900 go down on a ferry flight as well. Although they weren't cowboys like 3701, they missed a key checklist item that would have alerted them to their trim/rig situation. And of course the BUF accident happened which ended up being an industry-changing crash with FAR 117, new ATP rules, etc. "Flying Cheap" also reinforced the idea that Colgan was a shady operation that would force pilots to go, go, go. Even before the BUF crash, I had heard enough stories about that place that were scary enough to form my opinion stated above.
Be19, the difference between your examples is that experience wasn't really a factor in the crashes you mentioned. And after those crashes there weren't any landmark changes to aviation laws/rules. Unfortunately, the BUF crash was so bad that the entire industry was forced to change. New ATP rules, new hiring minimums, and new rest rules. And of course, the public outcry against Colgan pretty much ensured that the name Colgan could no longer live on in an airline. The CA lied to get to where he was that night. Sorry, but the flying public deserves better. The BUF FO actually talked on the CVR of some FOs in her class who were complaining they hadn't upgraded yet! 6 months in! And that she wanted to go through at least one winter before upgrading - which shows good judgement. It's sad what happened, but there are no excuses for that CA. This crash is entirely different than the crashes at LEX, NRT, LIT. Since I often get the emotion card thrown my way, I'd like to toss it back and say that since you work there you will be emotional over this topic as well.
