Pros
It is what you make out of it. You'll have good days and bad days. It's all dependent on your leadership. That can make or break the command. Medical is free, but can take a while to get seen. You'll meet a lot of new people and could travel around the world depending on your duty station. Education benefits and training.
Kontras
Medical can take a while to get seen, unless it's an emergency. If you're single, the pay isn't that great, but you don't have to much to worry about for bills if you live on base. If you're on sea duty billet, your work life balance will be terrible.
