Claude and Qwen 3 coder

Im so inexperienced in regards to coding but I have been using the max plan for 3-4 months I can't even remember but currently I have 4 subagents setup in claude code creating a Saas. Should I add a qwen 3 coder or cursor to improve code quality? Or any other advice you would give me. thanks!
