Most any quality call is capable of making all the sounds a Canada Goose makes with PRACTICE!!! When it comes to duck and goose call choices, they're a lot like a shotgun. You shoot it awhile but start missing a few birds so you decide to change to another shotgun to resolve the problem. Where just more PRACTICE would have most likely corrected the problem.
I do have to disagree with the Tmidenia's comments about the Long Honker goose call. The long honker was very popular about 10 years ago and everybody had one. It had great volume and was easy to learn the basics. But, every Canada Goose in North America has heard the Long Honker. I can tell when somebody is blowing one. It's initial semi-effectiveness has drastically worn off through the years. It is an easy to blow, double reed, entry level, "get their attention" type goose call. The Long Honker is incapable of making some of the subtler sounds that all of the aforementioned higher-end calls are capable of making.
I picked up the Sean Mann Shorty this year and like it a lot. I like the endless capabilities of a single reed call. Yes, they're much harder to learn to call, but their versatility is unmatched with the doubles (imho). I can easily switch volume, work close in grunts and clucks, soft purrs - all types of weird noises the Canadas make. And I can do it with one hand - which is a plus in my book. Although, I do use two hands to throw the sound in different directions.
Again, many of the aforementioned calls are mentioned because they are PROVEN producers. You usually see these higher-end calls in the hands of the experienced callers. Although I suppose these folks could call from a $2 dollar call reasonably well too! Also, many of the higher prices are for the more expensive materials. You don't need to have a call made out of Coccobbolla wood or whatever as it ain't gonna sound any better. Most of these calls are made to be handed down. The cheaper, polycarbonite calls work just as well.
Practice, practice, practice! Just when you think you're pretty good you'll hunt with somebody that REALLY knows how to blow a call. And then you will realize that it's now what you have in your hand that makes the difference. It's how much time you spend learning all those subtle notes (and when to use them)...
