Many use "the can" which you referred to and swear by it. Easy to use and operate. However if your looking to make doe and buck sounds with a call the HS True Talker would a great one to look into, it will allow you to switch calls by depressing bands on the call vs removing and moving a oring.

Personally I use mostly mature buck grunts and use the Knight and Hale EZ Grunter. If I want to replicate a doe or fawn I will use my voicebox instead of a manufactured call but again I rarely use these calls so buying "the can" or HS True Talker would mean carrying stuff I really don't need. I am not much of a blind caller unless rattling and the rattling is what I use to attract the calls I throw in are just more realism if you will. The rest of the time I will use a call in a visual only situation, the grunt or whistle will get it done here. I guess you must decide what calling or techniques you want to use then pick the calls or call that is best suited.

Rattling is one my favorite techniques as such I have tried the rattle box, rattle bags and fake horns. Nothing beats the real thing IMHO!!! One reason is tone, second is I rake trees and the ground when rattling to add again realism to the session(real horns work best here). I also don't smash my antler together but rather grind and tinkle them, yes I change the intensity and tone but by way of twisting my hands at different rates. So my vote goes for chopping off a set of real horns harvested or some fresh sheds found. Ones that lay our are not good as they sound hollow.

I also hunt the ground and use natural cover to help conceal me vs a blind.

Best of luck.
