I have a 6 1/2 quart Cuisinart, and it works very nicely for me. I have a smaller one too, but I like to make a larger amount, and then have it in the refrigerator for several days. So, I use the Cuisinart. I like the stainless steel finish of the cuisinart, as well as its controls. You can set it to low, or high temp, and use any amount of time in either of those settings. On some digital slow cookers, you can only run 2 to 4 hours on high, and 6 to 8 hours on low. The Rivals come to mind here. I recommend that you get one with manual controls and a timer that you can use at your option, which would give you more flexibility.
