CycloDS Evolution is the best, followed by Acekart 2. R4 was good in its' day, but is now retired and the market is saturated with clones that try to cash in on the success of the R4 (R4 2, R4 III, R4 SDHC, R4 Ultra, R6, N5 etc) that have variable compatibility compared to the original, and in the case of the N5 are known to permanently damage DSes. DSTT (TTDS) is another one to watch out for, the original is a good cart, but the fakes are becoming more and more ubiquitous and are also known to cause permanent damage.
