I currently have an up-to-date O3DSXL and MM3DSXL with Sky3DS but I'm interested in Gateway. Is it worth making the switch to have access to eshop content and homebrew? Should I just pick up an old 3DS or go to the trouble of hunting down a second N3DS? I know I wouldn't be able to do a system transfer from my current daily driver but would I at least be able to carry over my save data?
