Upon second listen, yeah Kanye does a good job on delievery.
But still, his vocals are SO fucking compressed and squashed. For those that dont know, when you record vocals the levels are up and down because no rapper stands still while rapping, or for example if the rapper needs to punch in somewhere the levels can be off and thus the verse needs to be compressed to make it sound level. Plus we just naturally say certain words louder. A compressor brings the lows up and the highs down and makes it all level, which is why the breaths are brought up and you can hear them more.
Everyone compresses, but Wayne is obviously the better rapper in regards to studio work and delivery because his vocals are pretty much natural and Kanye on the other hand has been compressed to all fuck to hide those level imperfections.
I mean this is pretty common sense if you consider Wayne grew up in the studio.
