Audio Intelligence VS. Walker Prelude LP Cleaning

I searched the archives for this and came up with no results under the analog threads. I have been using the Walker Prelude 4 step system and keep reading that a number of AudioGoners use the Audio Intelligence products and others use the Walker. I really am not interested in other brands at this point or home recipes, just a comparision between these two brands by someone who has used both. I have been using the Walker and it seems to work well, but it is time consuming and am wondering if the AI is better as it mentioned more often here in threads. As a side note I do use MoFi Enzyme on all new records and the Walker on used only. And once and a while I use L'Art du son on my older collection that was originally cleaned with Discwasher. I am not an alchemist just a little goofy on habits.
