I have had a few people ask me this question and I think it is a good one, so I wanted to answer it in a post. First of all, for anyone not sure what the difference is between Aura and LWC, you might want to checkout this post I did.
As for the answer….wait for it…..It depends. It depends on:
Like Salesforce Evangelists, I do think that LWC’s are the better alternative in terms of component performance, but if all you need to build are very simple components, then there is no reason why you cannot start with Aura and transition to LWC’s. To be entirely honest, LWC’s are more challenging to create for developers that are not already familiar with modern web development.
I hope this post helps anyone not sure about which technology to approach first. Feel free to reach out to me if you have additional questions or concerns.
