"When I work as a freelance with customers they'd say I'm the best"
Great. This means you are delivering to your customers which is what they care about. Whether the code is efficient or not, they probably dont care about that.So keep going there. You are doing great.
"When I work with fellow programmers on the other hand they'd say I am the worse"
To make a good programmer especially within other programmers, your items from 1-6 are good but i would not rank them necessarily in a specific sequence. They are all good to have.
