I'm pretty sure rendering-wise Vegas is a lot better. But apart from that After Effects is better for motion effects/graphics. But if you are literally just editing videos (e.g. YouTube videos) I think Premiere Pro is the best choice.
RE: Guys I need your advice about editing programs
For YouTube videos, etc., Premiere Pro is the best choice. However, After Effects is the main thing you should work on. I've used Premiere Pro and Vegas. Vegas had more crashes than Premiere Pro, but if PO does crash, it will likely have a back up ready.
