Hey Jean-Marc.
I'm going with the EX-30 because some of my work is quite large - but more importantly, I have plans to do larger pieces (they mean more scope to add extra detail, which I love). I'm currently working on my site, but if you want to see examples, try:

Hope this helps, and let me know what you decide.
Kindest Regards,
Nick.
