I wouldn't choose SQL Server just to be more cutting edge. I'd ask several key questions in making a decision.
1- How big is the database? What kind of growth do we expect? Will the proposed solution handle the size and growth?
2- How many users access the database? How many do so concurrently? Does the proposed solution improve accessibility?
3- Is my current solution reliable? Is it available when needed? Is security sufficient? Will the proposed solution improve reliability, availability and security?
4- How easily can I backup and restore data? Will the proposed solution improve on my current process?
5- How is current performance? Will another database provide greater performance?
6- Will we be creating more databases in the future that we can put in the new database system?
7- Can I justify the cost of upgrading?
Frankly, one database and a handful of tables wouldn't seem to justify SQL Server nor any of the other Server based database engines. I'd only recommend it if you needed a real performance boost.
However, SQL Server is a compelling choice for many reasons - low cost in its category, very reliable, excellent security model, high availability, excellent data protection, relatively easy to use, easier to administer than many similar products, etc.
