Arm Differences ...... ,etc.

I'm fairly new to the analog world and you've probably read some of my posts in the past. I've now got a good handle on brands and models, but now the technical.

What are the pros and cons of a unipivot arm compared to a gymbal pivot or non-unipivot? Which work more effectively with a suspended table? Does a type of cartridge lend itself more to a suspended table?

Your responses continue to be most enlightening. Thanks.
