aluminum rods vs. titanium rods: fatigue life

I did do a search on this subject. Got some information but, it's scattered among build threads and takes a while to dig through. So, if you don't mind I'd like to bring up the subject again.
This is not for an automotive application.

Question: All things being equal with the engine (rpm, horsepower, etc. ) which will last longer?. Aluminum connecting rods or titanium

Question: What has been some real world experience with either kind of rod?
such as:
blew up second pass on the 1/4,
been running circle track all season, no problems.
you'll be playing with the grandkids before a set of xx rods will fail.
