Quant related is considered the best, but there are a wide variety of internships considered 'competitive.' FAANG, or data sci/ML, and a ton of other areas.
Your banking internships are good, finance experience is handy and it is known that quant work is harder to come by. From what I can tell, not having quant work is not really a negative. It's just really helpful if you CAN get it beforehand. Almost no internship will give you and instant admit. Internships are helpful, but they don't appear to be the thing that will make or break your application.
So, yes, competitive (but not a golden ticket).
