First look at price. Of the carts listed, the two best lower-priced ones are the AK2 and the SCDS1. The two higher-priced carts are the CycloDS and Acekard RPG.
What you forget here ... is that your lower priced SCDS1 has the most features of all the Flashcarts.
I don't really understand why SCDS1 gets bashed so often.
So here are my 2 cents:
CycloDS has great support as the developers answer on forums themselves. (SCDS1 has also very good support, but no direct developer communication)
CycloDS has a responsive newbie friendly GUI. (SCDS1 has many configuration possibilities, but is slower and more cumbersome for newbies)
SCDS has MAAAAAAAANY features. It was the first to offer Realtime Saves and it is the only flashcart which offers realtime guides.
So it very much depends what is "the" best.
If you want an easy and great flashcart, and money does not matter, buy the Cyclo.
If you are an advanced user with a faster MicroSD card, buy a SCDS1.
If money is of big importance buy DSTT or if GUI is very important to you, buy the AceKard 2.
IMHO all these cards are good:
SCDS1, CycloDS, DSTT, AceKard2, EDGE, EZ Flash V
