If you are new to video editing, Sony Vegas is the easiest to learn to use and you can be editing your first project less than an hour. If you like paying a ransom, many editors rent Adobe Premiere. But the Premiere user interface is really confusing for the new editor so you may have your first project done in a day. If you are looking for a career in TV or movie editing, then you need to learn Avid. You may finish your first project after a week of cursing. (Avid editors enjoy their remarkably complex workflow because it guarantees them the big bucks).
I usually avoid these discussions because asking for opinions about Editing Software is like asking about religion.
There is no bad editing software, just bad editors. Your editing program is just a tool. If your tools don't do the job, it's time for a new tool.
The decision of which program to use depends on too many variables to be selected from other people's experiences.
I am certain that you will find few, if any unbiased responses to the question: "Which editor should I learn and use"? You are discovering the "Baby Duck Syndrome" which denotes the tendency for editors to "imprint" on the first system they learn, then judge other systems by their similarity to that first system. The result is that users generally prefer systems similar to those they learned on and dislike unfamiliar systems.
My advice is simple. Most of the modern NLE programs offer free trials and low-cost entry-level options (under $100):
There's dozens of others. All have some strengths and all have some limitations. They are all great and they all suck. It costs nothing but time to try all of them with a test project and select the one that best fits your needs.
Hope this helps.
