I've had experience with both. More so with the Snipe Pod, but I just purchased a Harris bipod. I don't know that there is a learning curve, but there is some getting used to. I can't speak for the bipod much as I've used it twice so far, once at the range and once in the field practicing. I have the tall one, so I think I can reasonably compare it to the tall, or sitting, Snipe Pod. Here is what I think so far:
Snipe Pod is definitely lighter
Bipod is more steady for me; a noticable difference and I have more experience with the Snipe Pod
Bipod is quicker to set up; with Snipe Pod, you'll be adjusting the width of the legs often
It's awkward to carry the Snipe Pod on your rifle while having you're rifle on your shoulder. You can do it, but the design of the Snipe Pod doesn't allow it to lay parrallel to the gun.
So far, other than the bulkiness of the bipod, I like it better. I'd rather the gun be bulky and heavy and me able to make a shot than the other way around. The Snipe Pod is basically shooting sticks attached to the rifle where as the bipod felt more solid.
This is just my opinion. The Snipe Pod is great, and definitely better for me that sticks. I actually just sold my Snipe Pod to a member here and will be using the Harris this year. We'll see how it goes.
