Bute vs. Banamine: What is the diff? Part I

So Harv has a bad stone bruise, I think, and Bute seems to result in dramatic improvement. I got to talking to someone about Bute vs Banamine, and ended up doing a little research.

True of both Banamine and Bute

• Both are  non-steroidal anti-inflammatory drug (NSAID)s. 
•  Both work by blocking prostaglandin production throughout the body. Blockage of prostaglandins results in decreased inflammation and pain, which is the desired effect.
• Unfortunately, blocking prostaglandin pathways also results in decreased blood flow to some parts of the body, including the lining of the intestines and the kidneys. Decreased blood flow damages the tissues, and results in death of kidney cells (renal papillary necrosis) and formation of ulcers throughout the gastrointestinal tract (lips, tongue, stomach, small intestine, and large intestine/colon).
• Both are risky when administered in particular situations, such as when a horse is dehydrated, shows signs of "tying up,"or is being treated with some types of injectable antibiotics. Side effects are also more common in foals and young horses.  
• Both carry GI risks.

I always wondered why people always use Bute when their horse is lame, never Banamine. So I did a little research. Here are a few sources.
