The short version is Voyager will also keep track of how many times I've up or down voted someone once user tagging is enabled. That's killer because it naturally tags users I've come into contact with even if I didn't set a specific tag for them. Then I start to recognize users from my up and down votes and maybe set a specific tag from there.

I still have Connect installed, I used it for my first year here since it was a close experience to Relay For Reddit, and the Dev is Canadian. I like the way Connect looks a little better, and it has a much nicer comment draft/preview system.

After running both together for a while, I found Voyager's entire user tagging system, with tracking and a summary of all tags and votes I've set, to be extremely valuable info. It has a lot of great features like Connect, but it's FOSS as well, so maybe a higher chance someone will improve the features I use in the future. I have stuck with it now for the last 9 months or so, it's great.
