I had the J&J one, the only effects I had were the day after I had fatigue and headache and chills a little but thats all
I had Moderna, and I had a very tough time. I had everything you could imagine for a week, fever, body ack, vomiting, nausea, severe headaches, dizziness, nervousness and I wished at that time that I didn't take the second shot, but the first one was easy with no problem. But after a week, I was fine.☺️
I also took the Pfizer with no side effects.

I had the Pfizer vaccine and did pretty good. Some side effects : lightheaded, headache and a little dizzy. It didn't last long though.
