[expert] Ext2 -> ReiserFS ?

[Sevatio]

I'm considering a switch from Ext2 to ReiserFS or anything better than 
Ext2.  Currently I'm LM8.0.  What's your opinion on the stability of the 
Reiser File System?  Is there an improvement for Ext2 on the horizon?  
What software would be best at converting the Ext2 partitions to 
ReiserFS?

TIA,
Sevatio
