I LOVE my ATG gun. It took a little getting used to, but it's well worth it. I use lots of tape because I'm so fearful of sending something that may come apart. For 3D item's it's the redline tape (a must) and for buttons and embellies it's either glue dots or Glossy Accents. I stock up on the Glossy Accents because it's a wonderful wet glue that dries super fast and it's ideal for me with paper piecing.
No matter what I think that it's generally whatever your preference. You just have to find your niche.
