If you would have to choose between the Holier Grail or Cathedral, which one would it be?

I want to buy 4 0r 5 EHX padals, and I want to cover reverb, delay, chorus/flanger, and definitely a POG2.I am also curious if the Flanger Hoax can do the Filter Matrix mode for chime-like shimmering chords, as Andy Summers does with the Electric Mistress?

Thanks much for an awesome board/community!
