well i personally enjoyed going through inferno pre-nerf and am glad i got to see all of it before 1.0.3, but i can't speak to the experience of any of the non-wizard classes so yeah.
it might actually be harder to get through inferno heavily undergeared now, though. at the time i first beat a number of the bosses, i don't think i would have been able to kill them before they raged if they had rage timers, and now they do. even someone like kulle i'm sure took me at least 5 minutes to kill, probably more. don't have any firsthand experience with this so it might actually be possible to beat them even if they rage, but i kind of doubt it's a realistic prospect.
but inferno as a whole is definitely easier now if you have decent equipment. essentially it's been rebalanced so that anyone will be able to beat inferno without having to spend a completely ridiculous amount of time farming, even if they're not great at the game or have one of the less favored classes. personally i would have preferred if they just balanced out the classes and still demanded a ton out of you to get through, but eh. some of the more specific tuning was good - soul rippers/lashers for example were just way out of line with everything else. heralds could kill you near instantly from offscreen. oppressors could kill you literally instantly from offscreen (maybe they still can but the blanket nerf might have covered that). but most other enemies could be handled with sufficient care...from range, anyway.
really regardless of what the absolute level of difficulty is, it was and still is too swingy, but blizzard has said they're happy with the level of randomness so welp. i mean there's a huge difference between getting a reasonable map and getting a horrible elite pack right at the area entrance where there's no room to deal with them at all.
