We used both. I brought a bassinnette and was given a cot, so it didn't cost us much cause we only had to get a cot mattress. I wanted a bassinette because the bub was going to be in with us for a while. The basinette we got had castor wheels on it which was great because I could wheel it around the house easy. It really is a personal choice though because some don't use basinettes at all and just use a cot and others co-sleep.
