Either start with Mistborn #1: The Final Empire or The Stormlight Archive #1: The Way of Kings. They are his main series, and generally regarded as his best stuff. Would probably recommend Mistborn as it's been finished, and the mainline story is only 3 books.

I think Elantris is his best. It's just that there's less of it (one book) than there is of the big series.

Elantris is great, but the end of the books is basically a gaping gap. Not entirely, but a bit like the story was cut off in the middle.
