Nice review. Sanderson released The Emperor's Soul freely in his website when it was nominated for the best novella Hugo award. It got it. This makes a fine entry point for Brandon Sanderson. it was for me. Then, Elantris. After that, no idea. Maybe this collection can become a new entry point?
Just a side note: Sanderson mentions that The Emperor's Soul is set int the world of Elantris, but there is no need to read Elantris first at all. Things might happen in a distant nation that never appears in Elantris, for all I know. If there are connections, they must be subtle and for the enjoyment of people who had read Elantris first.
Yeah, I'd say that's a good entry point. And true, you don't need to read Elantris for it, at the point Elantris ends the empires are still almost completely separate, and so far there is no sequel.
Elantris and Warbreaker are the novels that would be entry points, both being stand-alone so far. He's saying that sequels are planned, but probably way off, if ever, with all he has going at once.
Stormlight Archive is definitely his best work though, that's just amazing stuff, when I read the first 2 earlier this year it just felt like all his other works were practice for it, you see the best elements from the rest used here (not directly, of course, being a different world, albeit in the same universe, but those concepts, in their best form, applied to this world).
Mistborn, while epic in its own right, is a fair bit simpler if you analyze it. But with Mistborn he does this quite unheard of thing or moving a series forward in time, with the first trilogy in a typical fantasy-medieval world, the following four books (I think 4th isn't out yet) in sort of a fantasy-steampunk, then supposedly he has plans to move it into a modern, urban fantasy setting, and then fantasy-space opera in the end, which is where I'd guess he plans to tie together his worlds. But since I can't stomach modern settings, I'm thinking I'll stop after this current cycle, which was why I said I don't care for those connections.
Don't know anything about his other stuff.
But I really wouldn't call this collection as a possible entry point. Or maybe it might be, but only if you skip The Hope for Elantris (takes place at the end of Elantris, another character's story during those events, so spoiling and confusing without reading that first), Mistborn: Secret Archive (starts with the end of The Final Empire and rejoins the trilogy at the end of The Hero of Ages, continuing a character's story in parallel to the events in the books, so reading it without first reading those would completely spoil the original Mistborn trilogy and also be awfully confusing) and Edgedancer (takes place between Words of Radiance and Oathbringer, Lift got very little "screen time" in WoR and seems out of place there, but this starts from that bit and shows her story between those books, so again heavy spoilers and confusing without reading them).
PS: Later edit: Wait, Eleventh Metal and Allomancer Jak are also Mistborn spoilers, so that whole section is to be avoided if you take the collection as entry point.
I guess it is all about what sort of story appeals, as he is clearly a good writer.
His "signature" are the very... scientific magic systems, highly developed and detailed, and you can rather calculate what will happen if you know the... innards. The systems are very different between the worlds/series, but tied to each world's "shards" (think deities, but actually their energy, because they may be splintered/dead), which are connected (though you don't need to know that and at this point it's not exactly relevant).
At the same time, there are also moments when he shows true understanding of people and a lot of things they do and value. There's a lot about prejudice in Stormlight, religion is tackled in all, philosophy, ethics, customs, art, research...
