As far as convenience, faster learning curve (through instant feedback), cost, versatility (ability to change macro/wide angle lens underwater, talking point and shoot camera here, not digital SLR), ability to manipulate the pictures yourself and not relying on photolab to do the job right for you etc, digital camera will be hard to beat. Saying that, you will get better quality with shooting slide with SLR camera (at least for now, I imagine that the gap in quality is getting narrower and narrower).
So first, decide on your budget and what kind of photography you want to do, how much work/preparation you want to make etc.
Personally I stay with digital as I don't want to do all the works required by film SLR camera but a few of my friends do and the differences in quality is quite noticeable.
