Camera bags are pretty personal, so you may want to pick one for a wish list.
However, here are some good choices to look at.

My top pick across the entire line is ThinkTankPhoto. Designed by working pros, this brand has everything you need, and built to last.
From the Airport International, to the Street Walker, City Walker, and the new line of video bags, any product you get here, will be top-notch and just work.

I could stop, but I won’t.

There are some new contenders that are crushing it in certain areas.

The Peak Design Sling, is a perfect choice for a walk around street photographer, and the price is real right. Reviewed here.

Tenba makes a messenger bag, with a design that makes it a daily worker not only for cameras, but a full working bag your daily job use.

If a hard case is your need, because of checking bags, or needing a stool, there are some new options.
One, is the classic Pelican case is now available in a 40% lighter version, Pelican Air.Buy it with the TrekPak system. Don’t think you would be disappointed.

Put my hands on it, and it’s true. Hoisting it full of gear into an overhead will def cause less grunts from the weight.
What I’m most interested in seeing is a collaboration between SKB and ThinkTank Photo:

Combine a hard case, fitted with quality camera backpack, and you can fly with confidence, and when you get to your hotel, take out the backpack built out with your gear, and you’re ready to roll.

Like so much gear, you use the right bag for the right job. Any of the bags on this list will be a welcome addition to any photographers shooting life.
