I think mine is Magic Line with the very square corners. I love it, but you can use the Wilton pan too. It is just a matter of preference. It is actually the only one I have besides the 8 and 9 inch ones. The rest of my pans are Wilton and they work just fine. I got the Magic Line pans at an area cake supply store. I get the Wilton pans at Michaels.
Hope this helps.

Thanks. I would love to get the Magic Line but they are not available in my area. I was trying to decide if they would be worth the money and shipping to order them. I love the straight edges but thought maybe some people just cut the edges straight? I also can't decide if the 2" or 3" sides are preferable? Thanks again!
I only have 2" pans, but that is just me. If I want a taller cake, I make 2 layers. I can't remember how much I paid for that magic line pan, but I think it was around 15-20 dollars, not sure. If you think you will use it alot, it is worth it. That pan will last forever. I want to get the 11 x 15 because I actually use it more than anything. I don't cut off the corners though, just have more rounded corners on my cakes..

LOVE THEM!!!! 
I have the magic line pans and absolutely love them!! I bought the 11x18x3inch (i use this one for half-sheet cakes) for grad cakes and then the next size smaller for (1/4 sheet cakes)-8x12x2. I paid with tax and shipping $65.00 for both and was worth EVERY penny. They pop right out of the pans and are super strait on the edges!!! LOVE THEM!!!
