The Hellcat engine seems to not have any negative press. It's a robust iron block that can take more boost than stock. Ford's DOHC engines haven't faired so well. The FPC 5.2 in particular is known to consume oil badly and has shit the bed many many times. The Roadrunner engine in the Boss 302 was the last great coyote based engine Ford has made. Time will tell with the GT500 motor, but the Hellcat motor has around for a while now, FCA has put it in all kinds of vehicles in the last years and it's been proven to be reliable for the most part.
I think the 5.2L Voodoo is an outlier here. You can’t base all of the current Coyote offers against the short comings of one motor, which was highly experimental in of itself. There’s plenty of blown regular 5Ls out there making reliable power with just bolt on kits. They’re just as reliable as Stellantis offerings, even though they have significantly less OEM development.
