G-Drive Thunderbolt 3 vs. USB-C on Macbook Pro 2017

Which one is more suitable for photo and video backup on my Macbook Pro? Thunderbolt 3 worth the extra $$$? Thunderbolt 3 will work well to edit photos and videos straight off my macbook hard drive and onto an external G drive TB3 hard drive?

Thanks!!

They will have the same performance.
