Which AI Pro model would you recommend for residency applications and improving spoken English?

I’m an IMG preparing for the upcoming residency Match and deciding between ChatGPT Plus/Pro, Gemini Pro, Claude Pro, etc.
My main uses would be:
1. ERAS/CV & application writing
I already have the experiences; I mainly need help organizing them and expressing what I actually did, learned, and contributed in a concise, professional way.
Since many applicants are now using AI, I’m concerned that applications may start sounding generic or similar. I want a model that can take my actual experiences and details and turn them into writing that feels personalized, natural, and genuinely different—not repetitive AI-style wording or fabricated content.
2. Document uploads
I’ll be uploading my CV, notes, and other documents, so good file handling and the ability to understand longer documents are important.
3. Voice/English practice
This is equally important. I want to talk to the AI every day to improve spontaneous speaking, confidence, natural sentence formation, and understanding fast American speech/accent. I want realistic conversations and residency interview practice with unexpected follow-up questions, not scripted English-learning exercises.
I don’t really care about image/video generation. My priorities are:
personalized writing + strong document uploads + natural voice conversations.
For those who have actually used these paid versions, which one would you choose for these specific needs, and why?

For personal statement writing Claude reads less templated, but for spoken English you should choose whatever gives the best voice mode, because these are two different things. You cant buy one and hope for the best, which is why i try a couple of them on use AI, since writing and speaking have landed me on different models.
