I believe EPD issues a K-1, so if you were only buying a small position it might not be worth the bother of tracking the form when it comes tax season. AMLP did a reverse split some years ago and never recovered its original price, but a lot of companies in the industry had depressed earnings or losses.
I do think one should own some energy, but I don't have a strong opinion about these either way. I have owned some MLPs in the past but not at this time. I think the number of MLPs have dropped as some have restructured into C-corps after changes in tax laws some years ago. I have not followed that development closely or what impact it may have had on ETFs like AMLP.
