LA top end rebuild question

Good Day everyone.
I am in progress of rebuilding/ replacing the top end on my 340. I plan to replace from the cam up. My question is - has anyone experienced installing a Milodon gear drive and if so how did it come out? Was it a worthwhile upgrade? I was toying with the idea of replacing my double roller timing chain and gear set with one of these. I know it is quite a bit more $ than the typical chain/ gear. I was thinking about the longevity of a gear set vs a chain/ gear set. My current timing chain is a bit stretched and should be replaced anyway.

Thoughts?

Thanks in advance.

Thanks everyone for the great input on this discussion - gear drive vs timing chain set. There were some awesome and somewhat comical responses. I think I am going with a quality timing chain set. :)
