First of all, welcome to the forum!
Depends what you call " better bark ".

You can get that " Meteorite " black bark using water in the pan and going L&S or skip the water and foil the top of the pan, and cook at a higher heat like 275-300.
Take that till you like the color.
Bark ( to me) has more to do with the ingredients in the rub and the type of smoke-wood used.
Hickory,Pecan give it a more blond look. Cherry adds a red color and Oak is always darker.
If you want crunchy barky bark, then either the CS or that Aluminum pan you linked to will work.
I like to mess around and experiment with different things, so your thought process is valid, but you need to decide which one works for you.
