As much as I hate to say this, some of SP's recent experiments have simply failed. They might be innovative in a very objective sense, and none of it is bad. I for one love Ufabulum allot, but much of his newer stuff will probably not stand the test of time.
I think this is what sets RDJ apart from Tom imo. Richard's work is about as "timeless" as music comes and Syro doesn't seem to break that trend, while Tom was at his musical peak in the mid 90's to early 2000's. Allot of it sounds like just that. Music from the 90's to early 2000's.
