4x4 box with plaster ring vs standerd electrical box?

4x4 box with plaster ring vs standerd electrical box? what do you prefer? i want to use all 4x4 boxes but can not find a ceiling type 4x4 electric box that uses a plaster ring and has a between joist support arm. i like the 4x4 boxes because they can hold lots of slack wire. also what are the pros and cons of the 2 box styles.

Why not use a box designed for the application with plenty of room. This one has 21.5 cu in of space, and you shouldn't have a problem with wire cramping in it. Raco 21.5 cu. in. Old Work Ceiling Fan Box with Brace-937 at The Home Depot

Here is the box support you can use ,it depends on the situation as to what type of box to use,if you are hanging a ceiling fan the box and hanger must be fan rated,there are all sorts of plaster ring combinations,check out the Raco website.

The 4x4 mounts on the bar using a nut on the bar through the center knockout.

I prefer to use properly sized plastic boxes. You only need 6" of conductor past where the sheath enters the box. There is no point in trying to jam a couple of foot of wire in each box.

No such thing as a standard electrical box. Each box has a purpose and some have multiple purposes when used with the appropriate accessories.

When I do new or rewire work, I prefer to use fan-rated boxes for ceiling fixtures to save future headaches.

Isn't there somethng in the 2011 NEC about using fan rated boxes in areas that may get a fan in the future? I don't have a copy.

The requirement is if you install a fan rated box, you must run a three wire cable. (14/3, 12/3)

The main advantage of metal boxes is when they are used with a metallic wiring method or EMT conduit the grounds all bond together through the box fittings. The main advantage with plastic boxes is that the KOs and integrated clamps work very well with Romex. Plastic boxes are very good for residential use, not much need for metal except on unfinished basement or garage walls.
