Diaper bag

Hi moms! Do you have this kind of diaper bag? I can't decide which one I should get. My friend is going to buy it for me. do you have any other suggestion? I kinda like the one that becomes a bassinet but I'm worried that it is just too bulky and if it will be really useful. If I'm having a baby car I just think it really isn't needed but I also be using more of baby carrier. So, I don't really know. My lifestyle is just home, work, department stores. I rarely go on a trip. I'm really confused right now.
