Yeh thats quite a nice reece! I'm pretty sure its made on massive, possibly with all 3 oscillators running. Either that or another grittier reece layered over the top.
I don't think your attempt is far from it. Do you have a reece machine? If not, google it and download for free then I would try layering another reece on top of the one you've made, add chorus & a bit of Flange in their as well like you have down on the one you have so far.
reason thor is pretty perfect for this. Take 2 multi osc saw, detune them to get the harshness, put them both through a comb filter, automate the filter frequ to get the movement in pitch over time, put some screamm distortion/overdrive on it.
