Just for the heak of it, here is a comparison between the Spark, DJI Media Maker and MS Ice.
All 3 of these samples were stitched from the same 9 images and other than resampling to make them under 2mb, no post editing was done.
They were all resampled the same percentages.

Nice shot, only a bit hard to compare because of low res.

Cool shots

I prefer ICE, its easy to use and free. The spark takes way too long to stitch and format.

A little dark to compare stitching, but I also prefer ICE because my computer is more powerful and ICE gives me more options. I was expecting to find a picture of your finger with 3 stitches from a Spark related injury, so this is better.

Nice shots.
