Hi,
First of all, MIOPS has 3 different products as Smart Trigger, Mobile Remote and Mobile Dongle.
MIOPS Smart Trigger has long duration, rechargable and replacable LiOn battery so you can use it up to 4-5 days with one charge. Pluto uses LiPo battery like MIOPS Mobile Remote and they work around 24 hours with one charge.
MIOPS Smart Trigger has an LCD screen and buttons to make all setup so you don't need smartphone to make it working. It is also possible to make the same setup from smartphone. Pluto and MIOPS Mobile Remote needs smartphone to be able to work.
I think you have to check also the build quality of these triggers before decide about them. All of them have similar functionalities but if your first aim is doing high speed photography (popping balloons, breaking glasses, lightning strikes, bullets etc), MIOPS Smart Trigger will be the best choice. If you need this kind of triggers for creative photography and shutter release functions like Time-lapse or HDR photography etc then you can choose Mobile Remote or Pluto. As I know, MIOPS products have funded at succesfully at Kickstarter. You can also check the review of these brands to give the final decision.
I hope this helps to you.
Regards.
