I've taught adjunct in person 3 terms (for 2 different classes - Ethics & Business Law, with a class load of 2-3-3) and taught an online Health Law & the ACA Coursera class.
Pay is low. Hours can be long, particularly if you have a lot of assignments or a field where you need to grade things often. I found online that students were incredibly demanding at times (although some quite knowledgable and interested), which can be frustrating. Like when I didn't respond to a question w/a few hours, when I notified them I wouldn't be available for 24 hrs because a bomb went off in my town (Boston marathon).
That all said, a bonus paycheck is nice, I like knowing I'm helping educate students, I find I learn along with them at times.
I'd do it again after considering: pay / number of students / amount of grading / course design required (it's fun, but also time consuming)
ETA: The in-person was while I was on unemployment. Sadly, working many hours only netted me a small extra amount over what I would have gotten on unemployment, but at least I had something to do, gained some exp and resume line. Was a lawyer, so teaching was a voluntary move out of my field I didn't have to do and ironically, forced me to attend a hearing for my benefits near the end when I left for a full-time job. The online was last year, while working full time I applied for the Coursera gig through my old university that paid me for it.
