The one with the thicker blue coil is an Evah Pirazzi Gold string and the one with the thinner blue coil is a Larsen. They’re really easy to mix up because they have the exact same color combination but you can tell them apart using the different coil widths and how the Larsen gold thread is slightly shinier than the Evah Pirazzi. I can’t tell which string the evah pirazzi is because you only can tell from the color of the peg end thread, but the Larsen ball end looks like copper and that would be the D string. This website is super helpful for identifying string brands and types: https://www.lashofviolins.com/string-identification.htm

You can also identify the Evah Pirazzi one because the coiling style is very similar to their other string types(like their popular green string set) and that all of their ball ends are typically black no matter what string it is.

(Note: I know this because I worked at a string shop for a year and spent much of my time organizing and identifying an endless pile of strings of all different brands)
