I am sticking with Sense. That is one thing I really enjoy with HTC, and I am liking 3.0 on this phone. I might play with others, maybe.
I'm using File Expert, which works great for me. I've only tried two others though.
For remote desktop, I'm using androidvnc to connect to my TightVNC servers on my computers at home. All free/open source and work without a hitch, so far, for me.

To connect to my server via ssh (only port open to the internet for security) away from home, I use Connect Bot to set up an ssh tunnel on the phone first before connecting androidVNC to 127.0.0.1. Works well for me; I would recommend it for others using ssh to remote from the internet.
