姐你又错了 ：）

你罗列的这些 Java/.NET 技术基本上是 entry level 技术。十年资深挨踢资历，应该将自己定位在高端集成/构架方面。

个人认为，Java 也许比 .NET 更好些。原因：

1、系统集成路子宽；
2、most serious enterprise systems are based on Java platform on Linux/Unix；

regarding web, move to HTML 5, tools like ExtJS, etc; Struts /JSP/ASP are yesterday

J2EE not that hot any more. Focus more on high end core Java, such as high performance, high throughput, high availability: multi-core, multi threading, caching...

Spring might be very useful

on .NET, stay away from VB.NET/ASP, those are yesterday;

MVC is not specific/unique to .NET。MVC is just one of those architecture/design patterns, albeit one of the most used/useful.
