I think SW tanks are some what more challenging than FW. There are more things to monitor, stability of water parameters are more important, depending on how complex a system there are more equipment components (which can significantly increase cost compared to the FW counterpart) and certain live stock demand more or specific requirements; a greater scope of potential aquatic pests, etc. Going reef adds another level of complexity.
Now once all of this is firmly understood and requirements are met, etc, SW can indeed be as easy as FW.
Smaller SW tanks are harder to manage than larger tanks and sea horses are perhaps best reserved for experienced SW hobbyists. I wouldn't recommend them for someone just starting out in SW.
