It depends what your are looking for, what are your goals?
Is it enough when re-treating yourself some times or do you want a permanent solution?
Here are the different methods:

Short term hair removal methods are shaving, sugaring, waxing, threading and rotary epilators and last for a few days for shaving to up to 6 weeks for some of the other methods.

Some depilatory creams and thermicon heat systems last about 5 – 12 weeks.

Laser hair removal and electrolysis are permanent.
