If you have a combination of camera and computer/tech gear, Peak Design is a better choice. Their customizable capability allows you to configure it to your specific need for any given outing.
If you are referring to the Waterfield Executive Pro backback, I purchased that after hearing @MacSparky discuss it. It is fine for carrying your computer/tech and business supplies in but it is NOT configurable at all. What you see is what you get. It really has no space at all for carrying a DSLR or mirrorless camera system.
Also, a very disappointing quality control issue came up when the very first time I pulled the zipper to open the top compartment of the backpack, the small metal item that is wrapped around the end of the zipper pull to bundle the loose ends pulled off leaving the loose ends exposed and looking tacky.
Since the backpack was brand new I contacted Waterfield customer support and was told “Yeah, we’ve been getting reports of that happening. We will send you a new part…it is very easy to install.” No part has ever been received nor did Waterfield even offer an apology.
By contrast, Peak Design has a serial number on their products and a lifetime warranty. I have not had to use it personally, however I have heard of more than one person say that even after they had used a Peak Design Everyday backpack for over three years and it had shown some signs of normal wear and tear, they called Peak Design to see what could be done about it and they simply shipped them a BRAND NEW backpack at no charge…no questions asked!
It’s your choice, but Peak Design stands firmly behind every product they sell. Waterfield talks the talk, but I’m still sitting here with a backpack I paid a lot of money for that I doubt I will ever use. I will never buy another Waterfield product.
However my bitter personal experience aside, I still honestly believe a Peak Design Everyday backpack will serve you much better with camera gear.
