Well, since I only actually own a Cyclo DS Evolution (still waiting for my replacement, which was held up by the lunar new year) and a SCDS1 SDHC, I went with the Evolution as the GUI was faster, and it loaded ROMs/apps more quickly.
The SCDS1 SDHC is a close second place finisher as it also support realtime saves, AND (my favorite) soft-reset from just about all homebrew as well as ROMs. Major drawback being that it's a bit slower GUIwise and loading ROMs/apps, as well as using a database for save sizes. Also, a few games will ONLY work in "clean" mode(no patches) which means that it'll use the PSRAM to save games which will then be copied to the uSD when next reset or powered on.
Have you tried just turning off just the 'soft reset' for those few roms that don't work in 'enhanced/patch' mode ? that usually does the trick. Or once you have a save made in 'clean mode' and had at least one save to it, then the rom can use the enhanced mode.

Supercard is the only Flashcart Company that was accused (Year 2005 and before) for using External Memory (Memory Card) and today ALL are doing the same.
Supercard is the only Flashcart Company that updates its software for all the Cards frequently and they are durable for enough time. Rarely you meet new games that cannot be played. It has been a long time since the last that couldn't and it was fixed very soon.
Lastly, Supercard is would be the Flashcart Company that may introduce new software that adds something more to the game. Remember RealTimeSave on 05/12/2007 - 1st of all companies.
