there might have been some talk in here:
but generally speaking i tell most people to start where i did, with This Nation’s Saving Grace. you’ll get a range of answers but this one is probably the closest you’ll get to a consensus. tighter and poppier than their early work but retains enough of the early stuff’s weirdness. the albums immediately before and after operate in similar territory if you want more of the same after that.
then depending on what else you’re into:
if you’re into early 90s indie stuff like your Stone Roses (?) avatar would suggest then you might also enjoy Shift-Work. less heavy hitting than their best stuff but unusually melodic.
i found their debut Live at The Witch Trials quite accessible early on as well in a poppy punky sort of way.
Hex Enduction Hour might be their best but it’s a sprawling often messy thing that i had to build up to. but if you’re into noisy post-punk dive in. Perverted by Language has similarly long krautrock-indebted tracks but with a tighter, cleaner sound, which i love a lot.
alternatively if you don’t want to commit to a full album you could give the Slates EP a spin for a short blast of their early 80s post-punk.
there’s a decent compilation called 50,000 Fall Fans Can’t Be Wrong that gives a good overview as far up as 2003 or so but not sure how easy it is to find now, it isn’t on Spotify anymore. i made this fairly career spanning hour-long playlist for another thread a couple of months ago, it doesn’t necessarily focus on the most popular tracks and there’s loads of great stuff missing but gives an overview of some of my favourites, may or may not be of use:
