I have all 3 of these, luckily I got the CycloDS a couple months ago. The CycloDS was my 1st flashcart and its awesome, im glad i got it. Also I got all 3 of them from RHS, I highly recommend them, they are awesome. I personally use the G6 myself and my daughter uses the CycloDS. If you think 2Gb is enough for you, go with the G6, unless you are into homebrew, Ive heard the G6 is not the greatest for homebrew, but myself, i only play games with my G6, so i won't know.
