I think that in terms of essay writing for legal studies, there is no one answer that fits all situations.
if I were you, I would focus on one or two main strengths and weaknesses of your argument, rather than trying to cover everything. This will allow you to go into more depth and provide a more convincing argument. However, there may be times when it makes sense to mention multiple points. For example, if you are trying to refute a common misconception, it might be helpful to list several different arguments that debunk the myth. You can find essays related with your topic you need and make plan you like. I oten read and then write ideas for my reasearches. I hope I helped you. Good luck
