Each of them with their own set back. There is no way you will make a business proposal to venture capital and you think they are tong to invest in your business without T&C that will not direct or indirectly affect them. The truth of the matter is that investors can reject your business proposal even if the idea is very brilliant and realistic or they can agree with you but demand a percentage equity from the business that will make it hard for you to make, they may even offer to buy your idea if you are not smart enough in business deals.

While loan might have it own issues, if there is a place where you can get reasonable interest, it's better to go for it but I don't advice a new start up to start a business with because you don't know where you are going, you don't how the business will turn out and you don't know the uncertainties that will come up later in the business, this is why you need to use your own money preferably or money without any interest to finance the business.
