Not necessarily. It depends on your financial situation and goals. A conventional loan is ideal if you have good to excellent credit because your PMI costs and down payment can be lower. However, FHA is better if your credit score is on the lower side of the scale.
An FHA loan might also be a good choice if you're interested in applying for a loan in which you bundle your home improvement costs into the overall cost of the mortgage. For homes that need a lot of repairs, this is ideal.
