i don't think that a piece has to be necessarily readable to be hot, some of my favorite writers shit is unlegible if you don't know who it is before hand.
examples of some hot shit with less defined letters.
kaos
spie
code
paser
these are the cats i look up too, and imo these are some of the best piecers out there, along with totem,geser,kem5,lokus,supher etc.
