As difficult as it sometimes is to tweak to find a ‘good’ sound, the 4ms Noise Swash can sound like a sputtering freakshow when you find the right settings. It can sound great with nothing plugged into it. I built the smaller one (mini Swash?).
It's not the lushest phaser out there (I vote for the Mutron there), but the Blackout Whetstone is super tweaky and can get pretty out there. Also, anytime I need to make my guitar sound like a laser gun I rely on the Crowther Prunes n Custard.
