It’s easy to see why you feel that way. I think the Icon is probably the best player Hspin ever produced. I wouldn’t have expected that considering it was a budget model outsourced to India, instead of $100-$200 Swiss-made perfection. I know Hspin got to the point where they considered it a mistake to pursue budget models and wider audience yoyos, but not because they didn’t play amazingly. Classic shape, great finish, took silicone, played stable. I still play the Icon. It was a long time before I enjoyed another budget metal half as much.
To answer your broader question, I find that specific yoyos have come to define different eras of my thrower journey. Yoyos that vaulted to the prized spot in my case, became the go-to, by shining a little brighter than everything else in very subjective ways. Starting from when I already basically knew what I was doing as a yoyoer and not a novice anymore, a Pyro and modded Kickside dominated my case. There’s been quite a few others since then. ProtoStar, Chief, I use the sOMEThING Premiere an incredible amount since its release, and still others. I’ve always liked having favorites. I generally prefer getting to know certain yoyos really well over playing twenty different yoyos each and every day. And I think having those one or two go-to yoyos at any given time takes a lot of unpredictability and unfamiliarity out of the equation, making it more about the tricks.
