The CE-1 is definitely the thicker and lusher of the two, but both are awesome. The CE -2 is a nice middle ground between the ce-1 and scf. I have both an scf and ce-2 and the little blue boss box is the one on my board.
For me, the SCF wins. I've had both the CE-1 and CE-2, and I prefer the SCF for its versatility and the ability to set the mix. The latter is why I currently have a Mooer Ensemble King on my small board - it's in the CE-2 vein, but has a mix control
