In the context "good for PS CC and photography" don't forget a monitor. Laptop displays aren't really suited for that (in terms of quality; not size). Among what's available I suppose the MacBooks generally have the best displays, but it's still a very long way from a good monitor.
No opinions on the rest...
I know, monitor is the key - specially for digital photography, but not only for them. I take digital pictures more than 10 years. Nowadays work with analog pictures mostly, the analog material is scaned and than post processed on the computer. I suppose to use for most of post process my external Pro EIZO 22" which is the best screen I have ever had. Only outside when I travel or take outdoor picture to use for some temporary work (sometimes basic post process) is the screen of my laptop used.
I see. You're well covered, then (I have an Eizo myself).
What I try to solve now is to get some reliable laptop with appropriate performance for at least next 3 – 5 years. My main focus is photography, post process, working with scanned film photographs, webdesing (not often).
What you are going to need to focus on is Ram and CPU. One of the things that determines the shelf life of a Laptop is the motherboard. Nearly all other compontents are easily repaired or replaced and inexpensive enough, but not this one.
Asus has a good track record regarding motherobards and are used by gamers, who put computers through their paces almost as much as Designers and Photographers.
For Ram in Photoshop if you're using a high end DSLR Camera you need between 8GB-16GB of Ram.
Toshiba has great laptops in their Qosimo series.

You sound like you know what you're doing, but I'd just like to mention that "powerful" and "reliable" don't usually go with "laptop".
I realize many concerns go into a computer choice. "Portable" and "convenient" often figure into decisions, but a laptop will never equal a high-end desktop for doing graphics work with state-of-the-art software like Photoshop CC. There are just too many design compromises for size and power consumption.
That said, some of today's laptops kick heck out of yesteryear's desktops.
And I'll add, from personal experience, Apple makes reasonably solid, reliable laptops. Dell, not so much.
Apple makes excellent hardware. It's their marketing strategies, successful as they are, that give me this distinct feeling of being trapped in a dystopic science fiction novel.
Who would have thought? Windows, the rebel OS
Actually, the Macbook is my son's. He started with a Dell PC laptop, but after Dell had to replace everything for about the 4th time (not his fault) he decided to jump to the other camp. That laptop lasted him 6 years and I think two things ever had to be worked on - it needed a new power supply (despite the magnetic release, the cable frayed), and just recently he replaced the HDD.
We also have an iPad and an Apple TV, if that helps make you feel I'm less the enemy.
