I've done fish in cycling, but I don't recommend it to most people.
If you plant the tank heavily, it can cut down on cycling time.
I've had good luck with Bettas
The tank still needs to cycle, you still need to monitor it. I rarely lose fish, but I've been doing this a long time so I have confidence in my methods.
Fishless cycling is usually recommended for people that are new to aquariums. It is much easier on the fish but it can be boring to look at an empty tank which is why I recommend lots of plants. I can enjoy gardening until I can get my fish.
