Like RWS said, the rewards from hunting can be immense.
Hunting is much harder (if you do it right), but if you kill an animal, especially elk, the reward is much much bigger than catching fish.
That being said, the amount of time you can chase elk with an over the counter tag is limited to either 4 or 7 days, and it's a month for deer (5 weekends for kids, 4 for adults). Those season time limits are for rifle hunters, but bow hunters get WAY more time to hunt, with multiple seasons instead of just one chunk of time. There are also cow/ doe tags that can give you a very good chance at getting an animal if you do some research and don't put in for the most popular tags.
But fishing is a guarantee that every year at some point you will get some sort of fish, and there are opportunities year-round.
The thrill of hunting and fishing are both very subjective, and it's hard to decide what one is overall more thrilling, more fun, or just plain better.
So long story short, it's really up to the individual what is better. If you had to choose one and you could never do the other that would take some serious thinking to decide.
I personally won't say what one I think is better, simply because I don't have to decide between them, and I never want to. :lol:
