Why not? most everything at every Boulange in SF is awesome. (I might be a *little* biased)
The almond one is a bit dry, true,
but the plain one is perfect for dipping. And it is soft.
Then, they have the sugar +hazelnut croissant ... freaking sublime(the crust is a little dry/hard)
Yeah anyway in any case I'd have said "SF is pretty much fully sufficient for me for croissants if not the top"

Recently even a plain croissant from my corner coffee shop also works (depends on their supplier)
Back to the Boulanges , they have other food items that we like there. Like all their sweet tarts (the rectangular shaped ones) are full-on sublimeness.
As for Tartine? F- that, that's like waiting in
front of a Macintosh store! Due to that , and my only like.. 3 appearances at that place ... I cannot have sweet taste for that place.. only bitterness from crowds and elbow pushing.

Although they do seem to have pretty soft , sweet, well made stuff like lemon pies and what not.
Edit.. OK then.. for an out of city visit.. Tartine is probably pretty worth it. But still--the wait
