Terra cotta's the best IMO. Here's my largest semp Raspberry Ice. Not my favorite semp but I've got high hopes for it to overflow that pot. That pot was marked $12.99 at my local Wilco, but when the cashier rang it up she said it was $3.29. I asked here to check and make sure and she said it was right. So I went back and got three more. A four-for-the-price-of-one sale I guess. Man... I shoulda bough a dozen of 'em.
