Need your valuable inputs

Hi Ranchers,
I have 3 years and 6 months of experience in Java/J2EE.I started my career in a small firm.I got lots of exposure and I became an integral part of the product.I got a lot of visibility and responsibility.The work pressure was very high.It was normal to be working even after regular working hours.But I have enjoyed it because I had lots of friends there.
After serving 2 and half years there I decided to move on.The reason being the work was becoming monotonous.The work was not adding anything new to my skills.Also I wanted to get a brand name attached to my resume.

I joined one of the largest software MNC.The working hours is very flexible.I rarely had to work under pressure.But now I started to feel insecure.I feel I could take more challenges.Also I feel like I am one among the thousands.I am not getting responsibilities near to what I have enjoyed in my earlier company.
My doubts are, should I quit my current company and join a small firm? or Should I continue here?
Does any ranchers came through this situation?.What you did and how you rate your decision?

Thanks,
Anish
