I would suggest you download and install the X2 DEMO, which is free, and will not interfere with your X1 installation (they go to different install folders).
This way, you can try it all out for 30 days and make up your own mind on whether or not you want to upgrade.
All we can do is relay our own experiences, and ultimately your own evaluation holds the most weight.
Since it is free to evaluate X2 with the demo, I believe that to be a good approach to answering your question.
