Is it a PIA to splice through 12/4 in device box? Case in point, if you have 3 receptacles next to each other all on separate ckt and allowed to share neutral and you pull a 12/4 to the first device.

It depends on the cu. in of your box but it will be tight. You may be able to if your box has a minumum 27 cu.in. This allows a 12/4 and a 12/3 with a device grounds and a clamp-- not sure what you are using. Personally I would avoid it and put a jb above, if possible
The PIA factor does not into play in deciding where and when to splice, it comes from dealing with instructions someone who is not there and has no idea what you are dealing with trying to tell you what to do.

3 gang box? Talking about 3 receptacles a few feet apart. So 4x2-1/8 box for each recept.

Well, cubic inches aren't the problem. With a plaster ring you've got more than 32 - 33 cubes and, by my count, you need 25.
Are you pigtailing, or landing a lot of conductors on the device?
Got it, but you did say "if you have 3 receptacles next to each other" which sounded like a 3-gang to me.

That is how I would do it.

Use a 4'' square box for your first device with a 1-gang ring., and normal device box for your next two devices.
