Is working on a large project a good or a bad thing in the long run? [closed]

Question

In a large project you only get to use the technology necessary for that project; smaller projects come and go, and you need to learn more technologies.

On the other hand large projects are usually complex and thus hard; if you are used to hard projects then you should manage to perform well on smaller projects.

So, in the long term is it better to work on small or on large projects?
