I prefer 700X to everything else I have tried in 12 gauge. I shot 20 or 30 pounds of 452AA when it was new and substantially cheaper, but went back to 700X when Winchester increased prices. I have also used Red Dot, Green Dot, AA+, and now Clays, but still like 700X best. It seems more uniform at the light, extra light, ultra lite, and way, way, light target load level.
I have not tried WST and consider WSF to be a bit slow for my application in either 12 gauge or .45ACP.
I am at present loading .45ACP with some old 452AA, but when it is gone I will likely try Titegroup - I feel I owe Hodgdon some business after the help Phil Hodgdon gave with pistol loads for that 452AA - but it it does not offer advantages in metering or shooting, it will be back to the 700X for .45s, too.
