I've done a couple of other cybercrops, and cyberclasses in other crafts - all great fun!
UKS is definitely biggest and best all round because of what it is and what goes into it! I love the build-up and SB and Tree teasing. SMAX's superlative graphics and the themes are just so much fun - which go to make them the pinnacle of cybercropping!
However, I love to scrap at home in my jammies, so cybercrops are always good for me.....I get SO much done!
