Which one should I go for ?

I tried the khaki murph 42 and 38mm. Excuse the way the 38mm looks on my wrist cause I had to wear it loose to not damage the leather strap. I was wondering which fits me better ( I have a 7.5 inch wrist) Also what do you guys think about the pilot pioneer. Nobody posts about it a lot, and imo it looks the best out of the bunch ! (Slide 1- 42mm; slide 2 - 38mm; slide 3 - pilot pioneer)
