The difference is - they are running it as part of the United Kingdom - with money supplied by taxpayers including English taxpayers
.
Funnily enough if the Union is split - the English are as likely to say 'up yours' and give away as little as possible - and all the money will then be coming from Scottish taxpayers - huge difference
They will not be part of the EU (unless the rules are rewritten ) there will likely be a big pull out of businesses because of big uncertainties.
You only have to look at me - I am reluctant to buy a house in scotland in case the SNP do get independence - read that across to big business
