ZVEX Fuzz Factory vs Dr Freakenstein Chop Fuzz

Looking at buying something a little more extreme avd experimental and love the sound if both of these. Does anyone have experience with both who can add a little more to help me choose.

I've currently playing a Manson Meta MBH-2H so it already has a built in kill switch. Obviously the Chop Fuzz has tgat kill effect built in and can be manipulated, but am I getting something extra I dont need?

Honestly I cannot pick between them. I love the extremes of the ZVEX, tgat extrene feedback you can get. Can you get anywhere near this tone from the Chop Fuzz?

Im someone who has always loved to experiment with what you can get out if an instrument (so not surprising I love that Tom Morello/Matt Bellamy type of sound), so Wah, Whammy, Delay, a great Fuzz on top of the basics will always be in my set up. I'd always had more basic Fuzz pedals, but over the years with my baby breaking up, followed by growing up, family, wife, kids, house etc....my set up has dwindled. Somewhere down the line, my Big Muff went astray, so now im looking for something a littke more experimental.

Opnions welcone, if you've got any other suggestions. These are 2 that just stood out to me and honestly, I'm rebuilding from scratch
