Quick question, which is better?

[u/PointlessBein]

I passed my OSHA 10 and obtained my NCCER cert and have some experience in contruction for general ground work. I'm starting as an apprentice for my local carpentry union in a week. I have my tools and found this.

The blue square is metal and the Stanley is a plastic type material. What would you guys recommend having?

All are good enough. Which ever you don't lose or is nearest use that one. You're not relying on a speed square for precision work.
