Is there another way to say this?

[Harry Smith]

The best in life is worth waiting for...

 

[Grumpy]

How about "Everything comes to he/she who waits" or "The best is yet to come".

....although I'm not sure I'd subscribe to either ethos.

Thanks very much!

A better way would be to end in a period. That's the traditional way to end a sentence in English. By using an ellipsis, you seem to be implying that there is something left unsaid. Of course in any sentence there are things unsaid, but that doesn't justify an ellipsis.

In an case, I think "The best things in life are worth waiting for" is a better sentence.
