It depends what style you are looking for. The Seder Aruch has 3 Chalokim on Pesach, and one of them is a Hagodo Shel Pesach where he brings all minhogim and the reasons for everything with a mix of halocho, agodo and drush. Very nice.
R’ Shimshon Pincus’s hagodo is a bit heavier, but it extremely good if you are looking for a more hashkafic-mussar outlook on your Pesach.
Peshat – the Malbim has some very nice shtickelech. For that you can look in Toras Chaim where he brings all the Rishonim together – extremely interesting but generally not the sort of things you are looking to say over at the table.
