The best way is the one that work for your snake and is convenient for you and makes you comfortable.
F/T or Live it's about being knowledgeable about each methods and be responsible and figure out which one work best for you.
Feeding inside the enclosure is often recommended as moving a snake prior to feeding can lead to stress and refusal and will also make you more likely to get bit by an animal in feeding mode however if that work for your snake than again it's up to you.
Personally I feed in the enclosure and I feed live to all my BP, colubrids eats whatever is handy (often F/T from my surplus of rodents that I breed)
