Hi
I've made a mistake before by always using GPT-3.5 ...
It's not a mistake, it's a choice: GPT-3.5 is fine for most work, especially translation, it's already very good.
It's also fast and the cheapest.
GPT-4 has much better quality in general, and follows instructions better. It's also slower and a bit more expensive than GPT 3.5.
So using GPT3.5 is totally fine, unless you have a problem and something does not work well with it. In that case, try GPT 4.
But I would first try GPT 3.5 with these added instructions about not removing br tags.
If that does not work, try GPT4 without these instructions.
And if that does not work, try GPT 4 with additional instructions, and test other instructions as well.
Best regards
