There's no such thing.

Even if I could have only one at the house, there's at least a dozen pins I'd be happy with, probably dozens. Thinking that there's a "best" one, is just a path to unhappiness. It's also a great way to paint yourself into a corner and pay too much for a pin, thinking that this one pin on sale is the only one that's a viable choice.

Find a pin for sale near you, where you can check it out before buying it, which is being sold for a price that is both reasonable given the current market as well as within your budget, and which is one of the many pins that will bring you joy.

Then, go buy that one and enjoy the heck out of it, smug in the satisfaction that you didn't waste any time trying to figure out what was the one, single-best pin you could buy.
