Is there any reason not to get ACR hex bits?

Scott, Zypher is the OEM for Snap On last I knew. I like that website you linked to, tons of good stuff.
The Wera Diamond bits grip well. I compared directly to Wera non-diamond and there was a difference. But the Wera Laser tip is even better...... however it is only available on one piece screwdrivers.
I see no reason to get any type of non-grip bit.

I like the reduced diameter Phillips bits. They sink down in further into the Phillips slots and work especially well with shallow head Phillips screws. You can get them from Apex and Zephyr.

Apex and Zephyr have both held up well for me.

Omega is a great company. I too believe Zypher is the snap-on OEM, the first rumors of this was that they are the OEM for the Heavy Duty gold colored torx bits.
I can contest, the Zypher torx bits last just as long as the gold snap on bits. When the Snap ons wear out, I pop in a Zypher, and get the snap on warrantied when I can. Use the Zypher until it's worn out, toss it and throw the gold snap on back in.
I was breaking #3 impact driver bits on a weekly basis, not even worth warrantying via matco. I replace the zypher ACR #3 bits once or twice a year, when the start to twist.
Zypher saves me money and headache, doesn't fail by crumbling into shards, and doesn't ruin fasteners. I'm a big fan.
It's not rumor. If you look at the older Snap-on bits they have the Zephyr logo - the Z with a circle around it like in the photo but without the swoosh or airplane. Newer Snap-on bits do not have that marking.
ACR is a registered trademark of The Phillips Screw Company. Phillips claims:
"The ACR® Ribbed PHILLIPS® Cruciform Drive System advanced design keeps the driver securely mated to the screw during fastener removal, eliminating recess damage and damage to surrounding areas. The results are securely removed screws every time with lower costs, more productive workers and fewer drill outs."
Phillips claims ACR benefits also include:
- Improved removal without cam-out
- Off-angle driving ability
- Interlocks in removal requiring lower end load
- Reduces worker fatigue
- Reduces scarring surrounding panels

I keep picking up old US made Bosch ACR bits at my local electrical supply in their surplus section. I use them in my SO ratcheting screwdriver.
I do agree that the laser tips should be available as bits. The #2 Wera has removed screws like nothing else. Plus my local dealer will warranty them and I have never needed to.

I just looked up ACR bits and found an explanation and pictures. It is not what a lot of you are saying it is, at all. It is not a reduced diameter to fit deeper. There us no such thing as an ACR screw. What it is are raised ribs on the surface of the blades for a better grip. The original ACR name is registered to the Phillips company. There are grooves instead of ribs, used by some manufacturers. The diamond grit bits would seem to be a more sophisticated version of the same idea, texturing the blades for a better "bite". I was unfamiliar with the term so I had to search it.

Here is some info from the phillips website. The ribs on the bit are supposed to match ribs in the screw.

Thats why I was wondering if getting the ACR bit really helped or not on a standard phillips screw since I've never seen an ACR screw...

You're saying there's ribs inside the screw head as well?

I watched it. They're calling it the "ACR Phillips II System."
It seems to work well even though the ribs inside the screw head are at a right angle from the ribs on the driver tip. I don't know how it works that way but apparently it does.
Did you see that vintage Makita drill in its original teal color with the red battery? I miss those.
