Should I go for -44 or -51

I finally decided to do a 6 inch lift with 35s. I am still struggling with deciding-44 or -51 wheels. I want as wide wheels as possible with 6 inch lift and 35s without tons of trimming. Can anyone suggest how much -51 wider than -44? Do they look way wider or just a little bit difference? And also let me know if more negative offset I can fit. This is how my truck looks now with stock and 275/55R/20 and 20x9 0 offsets.

 

7mm, or about 1/4 inch.

 

What is that?

 

The difference in width in millimeters.
51-44=7

 

Haha ok I mean how they look in person. I have never seen them in person. We don’t have lots of modified trucks in Ohio. And it’s hard to tell by looking at pics
