I see...yes, I have the same inclination with leaving traces behind myself...although many of my early works leave such things as more a matter of "growing pains" than by intention...But I am getting better at scrutinizing minor details more effectively as time goes on. I understand about JW and Apo - even with my Alienware setup, the machine still struggles a bit to get renders completed. They truly are resource-intensive pacakges...Yes, I would certainly go with UF based on what I've seen others create with it, but I'm with you on the $$ issue... Now Mandelbulb really is a fun program - again, somewhat CPU-memory intensive, but well worth it - I can attest to that by experience. Best of luck with your future endeavors!
