Each to their own, but as Crestron DIN modules go, the DIN-8SW8-I is one of the lowest cost. You also now effectively get the (I) inputs free now too. As for the size, I appreciate the relay terminal spacing when I¡¯m mixing 240 V a.c. mains with low voltage switching on the same module. True the switching logic is different, but it¡¯s hardly complicated, and you get proper feedback (along with manual buttons on the unit and both manual and remote override).
