Hi, I'm thinking of taking up one of these activities. Any advice / comments ? Thanks

I would say, generally, kickboxing is better as a keep fit/class led sport.

Boxing IMO is for the fighters that want to get stuck in.

It depends on what you want out of it?

Both boxing and kick boxing are good for fitness and have a good sporting application. If its self-defence you are looking for kick boxing may gives you some more options. Its also a question of what will suite you best, so go out and get some first hand experience.

Try both and see what you prefer!
