Understanding ChatGPT vs Claude

I have been using ChatGPT as my executive assistant for awhile now. I bounce ideas off of it, work on strategy, flow through processes and challenge assumptions. ChatGPT has learned a lot about me so it pulls context in from lots of conversations. I have been hearing great things about Claude but never used it yet. Started playting but the limit on hte free plan is impossible to get a feel. I dont mind paying but not until its tested and I know its a good option for me.
