Armor stand vs armor shop?

[AV]

I know the look is different, but is the armor better with the armor shop? or you will just get more caps per day?

From this table they appear to be different in opening times and costs: http://fallout.wikia.com/wiki/Trading_post
I reckon the shop will offer higher level armor and produce more caps and hapiness than the stand
"There are 3 levels of each type, requiring an increasing amount of caps, materials and perk levels to build, but also yield more caps and have a wider selection of goods in stock."

Yes, the higher the "tier" -- stand, shop, emporium -- the greater the inventory, a better selection, longer opening hours, higher amount of caps to get from the trader when you dump crap onto him as we all try to do...

I also understand that there are some people you can recruit to operate the tier 3 shops and they then turn into tier 4 shops and can sell really high end stuff or hard to find stuff -- so restaurants have more than just instamash, general goods stores have lots of copper and fiber optic containing parts, etc. Even legendary items may be in these "tier 4" shops.
