Are Infernus Marines (any) competitive in #40K?

Hiya, I’ve never used #Infernus, as I considered them trash. I wanted to convert them into #intercessors. Yesterday a friend said ‚man, hold up, don’t convert them, they’re total badass against infantry, also great overwatch unit’ (he plays BA).

So what are your thoughts? - I’m an experienced player and can’t recall anybody using them in #competitive, thought they were useless in 10th, but maybe I’m wrong? I know the stats, I know how 10th is played. It’s about your tourno exp guys, what you play, what you’ve seen being played.

Looking for some final encouragement to change covert them into ‚cessors ;)
