Question: What is the difference between instanceof and isInstance?

Answer: instanceof is used to check to see if an object can be cast into a specified type without throwing a cast class exception. isInstance() determines if the specified object is
assignment-compatible with the object represented by this Class. This method is the dynamic equivalent of the Java language instanceof operator. The method returns true
if the specified Object argument is nonnull and can be cast to the reference type represented by this Class object without raising a ClassCastException. It returns false
otherwise.

I think of one more reason

In instanceof operator You can compare it to a named type only, and not to a Class object.
Like:
there is no way to cleverly automate objects by creating a Vector of Class objects and comparing it to those .

isInstance remove this problem and call instanceof operator dynamically. Source: CoolInterview.com
