I have a Delica 4, the Gray-Blue Zome Super Blue Black Blade Sprint Run version. It's a very nice knife. But, then I found that K390 wharnies are really nice, too. So, now I have two Delicas.
Even with 30+ Spyderco, all of the others are different models. The Delica is the first model where I have more than one. As for recommendations, I recommend more than one.
If you have other Spyderco, maybe there is a preference toward blade shapes, blade steels, PE vs SE. If you're around the water, a similar handled Salt may be better than the normal model. My collection grew because i wanted to experience the variety of Spyderco. Maybe you want a repeat of some feature you like in a different model. Or, maybe you want to try something new. You will need to determine which factors are important to you. Though my situation didn't allow it, if you can, visit a store and check some in hand. Maybe one will speak to you more than the others. As for best version, that may depend on your circumstances. And, if your circumstances change, what is best may change also. But, if that does happens, you will have more knowledge about what works or doesn't work for you. It will let you fine tune future selections. So, don't worry too much about being best forever, just best for now (maybe). You won't know for sure until you've used it a bit. Looking and feeling great on a table as in a YT review can be different than when you're cutting on something in real usage. Me cutting cardboard and opening boxes may be different than you cutting rope or some other material. Similarly, you using it for hard work every day on a job is different than an EDC carry that gets used once a week (or less). Factoring in how you will use it can help with getting a recommendation to match that usage.
