Cayenne vs Chile de Árbol
Both are long, thin and dried, but árbol keeps its bright red colour and a cleaner, nuttier heat; cayenne is the blunter, more generic one.

The difference
These two look almost the same in a jar and behave differently in a pan. Both are slender, thin-walled and made to be dried — which is why both dominate their respective spice trades. The chile de árbol is the Mexican one, and it holds a striking bright red long after drying, which is part of why it is used whole as a garnish and in oils where colour matters.
Cayenne is less a variety than a category. Most powder sold as cayenne is a blend, standardised for heat and colour rather than grown as a single cultivar, which is why cayenne powder tastes broadly similar wherever you buy it and rarely tastes of much beyond heat. Árbol, used whole, has a distinct character underneath the burn — nutty, slightly smoky, a little grassy.
In practice the choice is about form. Cayenne is what you want ground, in a rub or a sauce base where it disappears into the background. Árbol is what you want whole: toasted briefly, dropped into a pot of beans or a salsa de árbol, or steeped in oil where its colour comes out as much as its heat.
Can you substitute one for the other?
Yes, with a small loss. Cayenne powder in place of árbol works for heat but not for colour or flavour. Árbol in place of cayenne is an upgrade in almost every case, if you are prepared to toast and grind it yourself.
