You are right and not at the same time. Right telling that a redundant use of the keywords is not generating benefits (instead, it can look simply spammy)... not, because the title you are suggesting in not "exciting".
Remember that Titles are the first line of a Search Snippet. Therefore it should have to be crafted wisely:
- In order to focus Search Engines on your page's main keyword;
- In order to push the searchers into clicking your result and no other.
I usually suggest to think to Title as they where the Page Tagline. This also make easier its use into the same content of the page itself, as the HTML Title usually is converted to the H1 Title by many CMS.
Therefore, in your case, a Title could be:
Life Insurance? Ask now a life insurance quote to Axa Sunlife
And the Meta Description would renforce the Title call to action, maybe citing the main competitive advantage of the Axa Sunlife life insurance.
Ciao and I hope this helps
