Best Database Choice? (easiest to use, distribute etc)

I have access.. but know that its prone to corruption etc..

MySQL is installed, but i started thinking there might be a better solution?
MS SQL Express?
SQLLite?

I just need to be able to install it locally without much hassle and be able to move database (structure and data) to another machine when done

IM thinking MS Sql since VS is their 'baby' they might play well together...

thanks!
