Photoshop Stitching

I was wondering what must people use to stitch with in Photoshop?? I Have some experience with the software but I have never made any sequence shots before, So I was wondering what tools in Photoshop people use??? For example, Do people use the Megnetic marquee tool, Clone Stamp, or Magic Wand??? Do you use a combination of all of these?? Let me know what you guys think works the cleanest and best way to do it, Thanks
