I own both the Intellijel Morgasmatron and the Joranalogue Filter 8.

If I had to pick one and give up the other, I'd keep the Morgasmatron. The Morg is actually TWO multi-mode filters that can be used independently, in series, or in parallel. The Filter 8 has just one set of controls/inputs that feeds 8 types of simultaneously available filters. The Filter 8 offers more precision, better modulation options, etc. But it's definitely not as flexible.

I don't regret either of them. But being able to call up a low-pass AND high-pass filter is much more common for me than need a 6,12,18, and 24 dB per octave filter all in the same module.
