Well heres another comparison as i have nothing else better to do at this hour
Out of the reloader, the pulse and the vlocity:
The vlocity is the lightest
The pulse is the most effecient
The reloader is the only one with a rip drive (if the batteries fail in the pulse or vlocity, your screwed)
The vlocity has the highest capacity (depending on paint size)
The pulse is covered by a lifetime warentee (whatever happens to it, it will be replaced for free)
The reloader has tonnes of upgrades and custom parts
The vlocity is slightly slimmer than the others
The pulse has the shortest feedneck bringing it closer to the marker and making it less of a target
The reloader is easy to take apart and scrub (though the pulse is easier due to the removable tray)
There ya go, enjoy
