There is a slightly better question to ask and that is what is your desired outcome? If you are trying to get some college credit, knock off some prerequisites, or just get accepted to T20 schools, the answer will be very different.
Of the 3 choices you present, Dual Enrollment taught at your high school by a HS teacher is the least impressive overall. If it is administered by public instate community college, it is very likely that private schools and out of state publics will not give any credit. Compare that with Dual Enrollment taught on a college campus which may translate to some consideration regarding placement and may/may not give college credit. AP credit is dependent on test score and policies at colleges for granting credit or placement.
A good rule of thumb is the more selective the college, the more restrictive the credit/placement policies. Since you asked purely about rigor, that is a question for your guidance counselor because that is something they note on their form that accompanies your application. They will have criteria about what constitutes the most demanding courseload offered by your school.
