Excellence – The Ben Ish Chai is good reading. However, for Sefardim, most are noheg to follow Rav Ovadia in Halacha, so it is better to learn Yalkut Yosef if you want to know present day Sefardi halacha. The Ben Ish Chai was noted to be machmir in several areas and Rav Ovadia would bring down his deiya and state “those that would like to follow like that Tov Alav Bracha”.
I’m not saying not to learn the Ben Ish Chai. By all means do. I’m just stating that if someone wants to know contemporary Sefardi halacha better to look at Yalkut Yosef.
