I’m a fan of My GoRuck Gr1.
It’s traveled with me all over the world and looks just as good as day 1. The (minimal) molle is super nice so I can add things as needed. I needed a tripod holder. So I used the side molle for a water bottle holder and sewed on a retaining strap and have that. There’s very basic internal storage inside. But also molle so if you need more you can just attach it.
Also when I feel like I need a new bag. I just swap out the patch and it refreshes the look enough for me. Enough to scratch that itch.
