The three markers you have mentioned work totally different mate
Autococker: Basically a pump marker, that has had the pump handle replaced with a automatic cocking system, hence the name. An electronic cocker has simply replaced the mechanical autococking system with an electronic one. Few years ago these were top of the range, and you could basically build one from aftermarket parts, but lately they have gone out of fashion as most of them are heavy, and werent exactly new user friendly
.
Shocker: probably most simple concept of the three markers. rather than me hashing it over, this website is the bible for all things smart parts, and will explain it better
Clicky
Been around longer then the Ego, so more aftermarket parts, and a number of private labels, both of the new and old style marker, the SFT does have a problem shooting black shelled paint due to the reflective eye system, and the anno sometimes has been known to wear and screws to strip as softer aluminium is used. Performance wise will shoot as fast as you can pull the trigger, and will place the balls on the target, Old markers were gas hogs, newer ones come with high efficiency bolt kits.
Ego: All incarnations work the same way, have similarits to a spyder in some ways if i remember, just using a solonoid instead of springs, fair few different bits available from planet and others, and seem at the moment to be flavour of the month. Again accurate and fast, and probably have the edge on shockers in efficiency.
As the man says though, try them all and see what u like, otherwise everyone would be shooting the same marker...
Hope that helps.
