but ultimately VS at the end

The more sophisticated is "ultimately" but usage choice depends on the context.

Thank you for your help.
Can you give me two examples shows the difference please?

"Ultimately, I am going to be the winner."

VS.

"I am going to be the winner at the end."

Which sounds better to you? That's the difference - both mean the same more or less...When are you taking your IELTS??

vdbWhich sounds better to you?

It depends on the context:

We are playing a tennis match today. We are evenly matched, and the score will seesaw back and forth, but I am going to be the winner at the end.

It's been a long struggle with this disease, and I won't let it defeat me. Ultimately, I am going to be the winner.

Broadly speaking, in the end is more likely than at the end.

Thank you for your reply.
This sentence "Ultimately, I am going to be the winner." seems more nature for me.

I am planning to take the exam at/in the beginning of March. The problem is I need to get 7 overall and not less than 6 on each.

Thank you for your help.
Which is better "Broadly speaking" or "In general"?
Can I say "Everything is fine from my side, so please check at your end or in your end"?

vdbWhen are you taking your IELTS??

That's an interesting question. Do you think I should take the IELTS?

Thank you for your help.

Ultimately is fine, but less common in spoken English.

Which is better "Broadly speaking" or "In general"? Both are fine. Much depends on the context.

Can I say "Everything is fine from my side, so please check at your end or in your end"?
Say 'at', not 'in'.
