I had this same question about a week ago. After deliberating and reading many posts about the two cutters I have decided on the Portrait, I think! I like that the machine itself is smaller, I don't need the SD slot because it will always be by my computer, I would most likely not cut 12x12 backgrounds because I think it would be very busy and I'm a simpler kinda scrapper, I can cut 8 x 12 on it and can them cut a 12" title if I wanted to, I like the price of the Portrait and Silhouette should have a nice deal on them on Black Friday. So for all of these reasons, I'm going to go with the Portrait. No need for the biggest and best for me for this machine. Good luck on your decision and most of all, have fun with it when you receive it!!
