Personally I like fishless cycling best. The main benefit to me is you don't have to worry about daily water changes to keep the fish healthy/alive until its cycled. A downside is that you won't have fish to look at for awhile. If you're good about monitoring water parameters and doing daily water changes then you might try fish in cycling.
There's articles on this website for both fishless and fish in cycling. You might want to read through both and see what works best for you.
