We have a huge crockpot, and I love it. Depending on what you make, you could end up with just a couple of days of leftovers or with plenty to freeze and eat later (which is always nice when you don't feel like cooking). In your shoes I'd probably keep the big one just to have the option of making more (like if you go to a potluck or have a large group over and want to make something big). But if storage is an issue, a smaller one might be better too. That's my only complaint with the big one.
