I don't claim to be a super mechanic, just a regular joe blow who makes mistakes here and there and bumbles my way along, but honestly, setting up triples has just be non eventful, as is using them.
that aside, which Im sure you dont want to hear ;-)
as per your question, with large cassettes in 10 and 11 speed nowadays, (42t up to 50t) a reasonable double can have reasonable low and high ranges, but a triple will always have the advantage of a wider range often combined with a tighter cassette to boot--win win.
give some ideas of what you are thinking of using, component wise.
