Help Choosing First Rifle

Hey everyone, as the title says, I’m trying to decide on my first AR, and I’m pretty new to the platform.
I’ve spent a lot of time watching YouTube videos and reading through posts comparing the different SR-15 variants, and I’ve narrowed it down to a few options. I was hoping to get some input from people who actually own or have experience with them.
Since this will be my first AR, I’d rather buy once, cry once and get something that’s considered one of the best. That’s why I’m leaning toward one of the newer KS series rifles.
I also know I want to run it suppressed. From what I’ve read, the KS-3 seems to perform pretty well with a suppressor, but I’d love to hear from people who have firsthand experience.
Does anyone have any insight that would either reinforce going with the KS-3 or point me toward a different SR-15 variant? Any advice is appreciated.
