^^^ I am not a huge fan of that kind of stuff - the only reason being is I get bored of tech-anything if there isn't interesting melodies intertwined. I'll qualify that by saying I'm not versed in their discographies extensively.
-> This is one reason I like Necrophagist so much, is there are some great melodies and neo-classical influence there.

If you like Planet X, check out Virgil Donati's on the Verge. The focus is on the drums (he is the drummer) but it's so damn good.
