I have maybe a dozen different bags or cases. I have a couple primary ones, but I might use one or two of the others, depending on my needs for the trip/job.
There are always compromises and a lot of it is personal preference. I have a backpack, which is great for travel or hiking, even just tossing in the car. But it's a pain it get the gear in and out quickly, or to get it on or off quickly. A shoulder bag is much better for that, but harder to carry for a long time.

If you are looking for a bag, you haven't gotten serious yet about this whole photography thing yet. Like Big Mike, I have a several bags and cases depending on the need. Each serves a different purpose.
