WW-748 and H-335 are very close, at minimum. Their ancestors were likely WC-844 (mil-spec ball powder for 5.56 x 45) and/or WC-846 (mil-spec ball powder for 7.62 x 51). Lot-to-lot variations? Say it ain't so! 
I use a lot of ball/spherical powders, owing to their consistent metering and decent performances in calibers appropriate for their respective burn rates.
The source for my caveats on low-density loads of ball powder was the late Leo Reyes, my mentor for reloading and bullet casting. His background prior to working with my Dad at the Coroner's Office was as an ordnance staff NCO. He didn't care much for ball powders, and his view was that the deterrent coatings used to regulate their burn rate did their best work in higher-density loadings, with WW-231/HP-38 being the sole exception.

Not only high density, but also very narrow pressure range. Anyone who shot those eastern bloc machinegun powders in .308 cases will tell you about scraping black stuff out of the barrel.

Funny. When I purchased my first high powered hunting rifle in 1970 it was a 788 Remington in 308W. All the press said "the powder" for it was IMR 4064. Honorable mention were WW 748 and BLC2. I tried 4064 and with 150 and 165gr. bullets and never found anything but lack luster performance accuracy wise. I bought a pound of 748 and BLC2 to give them a try.....748 turned out to be magic. I still have 1/2 of that can of BLC2....
47gr. of 748 behind a Hornady 150gr. interlock has been a deadly combination for all these years. Accurate, burns clean, decent velocity without beating up me or the gun, and it kills deer like the hammer of Thor....I like it. I killed a nice little buck with that same rifle last year, same load, and it will still put 5 of them into an inch or so at 100yds. I only have a straight 4x scope on it and I just can't shoot any better than that.
I have heard about the powder being sensitive to cold weather. I have not found that to be so....down to -9F. I have about 12 lbs of 748 on hand. I use it in the 7x30 Waters, some in the 223R and of course my 308W. At my age I think I have enough to last me "a while."

Varget showed me nothing, had to try it when it came out.
Agree here also, nothing magic about varget only plus I can give is it seems to burn clean, not bad as far as temp stable from my own personal experience and lends itself to downloading fairly well for the 150gn 308 cast but as a wise man once said - "as always your mileage may vary....." well maybe he said it more than once.....

So..... synopsis I am taking from all this, and and some other research.
H-335
From center fire.22 to short action .30 cal. 2800-3800fps. 10 to 24 inch barrels. = grand possibilities
Other then that.
So many other; more suited, powders out there. For outside this window.
So beyond this, not worth the effort.

I have heard say that above 60 grain CFE-223 is a bit more accurate, and cleaner.

I use a lot of CFE-223, pistol, and black its a bit higher on the pressure scale of powders but gives you higher velocity's and accurate loads, seems to burn pretty clean and lot to lot its been pretty steady. Wouldn't hesitate to recommend

I like H-335 in my full house 30-30 170 gr. cast lead loads. It's also a good powder for cast lead loads in 7.62 × 39 but I have other powders that give me a better bang for my buck but I have it if I ever need it for that particular cartridge.
I've used H335 for .223/5.56 since I started loading for that cartridge in 1975. Loaded up 60rds using a drop tube for IMR3031. That's the last time I used stick powder in the .223, it's been H335 or BL-C2 if no H335 available.
Not long after the RCBS lil Dandy came out I discovered that the largest rotor threw the same powder charge that I used for 55gr bullets.
Tried it in .30-30 a bit too, just didn't give me the accuracy I wanted.

I love the Idea of 1 powder for multiple guns, or loads. Considering I currently store all my loading stuff in a 4x4 corner of the living room. So reason for this thread. Sometimes I am willing to sacrifice a little accuracy, for , the ability to do more with less.

H335 has worked well in my 5.56 with 1x9 barrel twist and 50&55gr vmax bullets. But H322 and even imr 4198 beats h335 in my other 5.56 with same bullets.
