There's a wave of this particular type of Fall-influenced post-punk atm and of those bands Fontaines happen to be one of the ones who have got the most industry purchase, particularly in the US. I wouldn't have said they were the best or most interesting of that crop of bands though, let alone in guitar music more broadly.
And tbh I'm starting to get tired of the sheer glut of homogenous post-punk bands trying to sound like Mark E Smith tribute acts. It's becoming reminiscent of the landfill indie of the early 00's, with this sound being the default template for what mediocre indie bands sound like. After a while it starts to put you off even the better ones.
