It has been years since I have used either of these pedals but have been thinking lately of adding one. I think I had the effect they created backwards until last night when I was going through old threads. I thought a phase shifter would produce the big, slow "woosh" plus other sounds while the flanger produced a "watery" effect. But last night I found an old thread where Mystic Boo had links to an MXR 117 (?) and a Small Stone phase shifter. The MXR produced the big woosh effect which I love and the Small Stone produced the "watery" effect. Do phase shifters pretty much stay to the watery effect? I loved the MXR!
