I was certainly content with the results at first but after much serious practice I found it less and less effective. I'd recommend most people to try serious meditation but think that its important to manage expectations - a tiny proportion of Westerners that start with meditation feel enough benefit to continue it for the following years.
In my own experience, Yoga had more noticeable effects and a better 'buzz' - this as someone that also gave up Yoga a few years ago. The advantage of Yoga is that you also feel healthy. I hope fight off my current laziness and restart Yoga again.
