I had the Shingrix several years ago. For me the side effects were strong, I spent a week afterwards in bed, like a really bad hangover.
However my MIL had shingles so I think it was a good tradeoff.
I got minor rash outbreaks all over my body and felt slightly ill and feverish.
I was completely back to normal after 48 hours.
Before the vax, I had two serious outbreaks of sun-related shingles, so I was glad to take the vax risk.
