Should I read the manga and watch the anime as well

I kinda want to read ahead with the manga because the anime is kinda slow right now. does it make sense to read ahead of the anime from the manga and continue watching when episodes come out? I know the manga is super far ahead right? Does anyone else do this?

Edit: Okay so I didn’t know it’s really the LN that’s ahead not particularly the manga. But I may just wait for the anime to release still because it’s just spoiling it. Thanks for the heads up from the comments
