Which teeth is better to extract on lower jaw left 1st incisor or right premolar (4th) tooth? (Photo)

Hi, I have 2 options: to extract 1st incisor on the left lower jaw or to extract 4th tooth on the right side so that teeth have space to line up well. I was told many different opinions but can't make a final decision. I trust my doctor but I want to be 100% sure before extraction as it can't be reversed afterwards. Please give your opinion.
