New Program?

I know this is FAQ type of question, but I needed some ‘up to date’ answers as to which program to use, Im more of a Premiere Pro Junkie and works everything with Premier Pro. I was wondering if its worth learning this DaVinci program? I have read that it uses less ram and computer power than Premiere Pro yet still delivers the same quality. Is this true? How hard is it to learn tho? Will I be able to save so much time editing and color grading in this program than Premier?

I want to read some insights. Thank you!
