What grid should I use in my case?

Question

HTML

Hello colleagues!
I am confused. I need your help.
You need a grid that is easily customizable (padding, number of columns). Bootstrap did not fit, it is very dependent on the html structure and is poorly configured.
Googling, I found Susy, everything seems to be fine, but it's bad that there are no classes like column-6 and I'm also afraid of constantly adding .last to the last element.
What do you advise? We need a system that can be configured twice in different ways, that one grid was with gutter 20, and the other with gutter 5, for example.
Thank you.
