"Is it worth" is exactly the question that should drive this kind of discussion.
And it can be answered _after_ evaluating, or even guessing the "value" of the
available options.

But you entered the discussion _again_ with _your_ answer, stating _again_
that "we" "would like to replace it".

Can you please try to use a less overbearing approach? Like, presenting the
options, stating your personal opinion on their respective values, give people the
impression they have a chance to give their views, and when the dust has settled,
give the impression of making an educated guess on the result and "decide" _then_?

"Thank you."
