Yes, I use outboard gear. Other than preamps (obviously) it's mainly EQ and dynamics. I don't use any of my digital fxs boxes anymore. I keep them in the rack for the very rare oddball thing, like, once a year LOL.
I would say that if you are starting out, focus on outboard gear you can use while tracking in addition to mixing. You can get a lot more mileage out of it that way. Plus, when mixing, you can only use a box once.
One of the things I do frequently to deal with a busy schedule and having to switch mix projects frequently is when I feel like I have a part dialed in and a pretty solid mix, I'll print back any hardware that can be printed back. That usually means anything that's not on a buss (because of getting multiple signals making changes particularly difficult). So a common scenario for me is to have the lead vocal all hardware with EQ and compression. When I think the mix is "there" and I am going to either sleep on it or send it for approval and I consider the odds of needing to change those settings about 1 out or a 100, I'll print it back to a new track. I'll copy all the automation to the new track and print the straight audio. That way, if I need to later go back and change it, I can easily. But it avoids the inevetable slowdown when switching projects and having to write everythign down and the reset all the gear for the other song. Now I can just load the other song. It also avoids the scary situation that all pros have experienced where you discover upon recalling a mix, that you wrote down the WRONG setting LOL.
This all said, software is getting sooooooo damn good now. So I would also focus on gear that does something you can't really achieve in the box as well. Just getting outboard gear to impress your friends doesn't do you any good.
