Asking for opinions about Editing Software is like asking about religion.
The decision of which program to use depends on too many variables to be selected from other people's experiences. You edit with your brain - the NLE is just a tool.
I am absolutely certain that you will find few 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:
Sony Vegas:
Sony Creative Software - Download: Trials and Demos
Avid:
Artist Suite - Creative tools for audio, video and live sound production
Premiere:

Lightworks:

There's dozens of others. All have some strengths and all have some limitations. It costs nothing but time to try all of them with a test project and select the one that best fits your needs.
Finally: Use what works for you and will make your clients happy. Try them out. All the NLE programs are great... and they all suck! They are just tools and in today's world they all will get the job done. But as tools go, some are better than others for certain jobs. The right answer for me could be the wrong one for you.
Hope this helps.
