GnuPG front ends

[Patton Echols]

It looks like there are a couple of GUI front ends available for GnuPG.  
Looking at the web sites, It appears that Seahorse is more full featured 
than GPA, though my needs are fairly small.  I'd expect some level of 
key manager and I  want to be able to encrypt / sign clipboard contents 
or point to file, my choice.  Any thoughts about which might be a better 
choice?

Also, I'd expect that if I tried GPA, for example.  then uninstalled it 
and tried seahorse, keyrings etc would be there as soon as installed, 
both should be looking for the standard GnuPG file locations, right?

Any other thoughts before I get started? 

Thanks
