Ha! Nice thread! And almost brings up a history of my hobby.
I'm a cup-half-full sort of person, so the good ones:
My very first project (though I didn't really know at the time) was in tulipwood. I made fitted wardrobes. They're terrible...well, the doors are gappy. Looked at another way, they are a triumph of hope over experience and I learned soooo much. As to the timber - clean grain, cuts crisply, doesn't dull tools unduly or chip-out or fray, and takes paint well. Too bland to stand alone.
I made a couple of beside tables in plane (lacewood) - hard to plane without lifting chips, but otherwise well behaved.
Black walnut table - crisp, clean, polishes perfectly. What's not to love? Well, the price.
Beech bookcase - seems prone to twist/bow/cup? As soon as I cut a length it was bowed, even in the wider measurement. Made a nice bed out of some though (pictures prior)
Oak. Just finished a patio table and 10 chairs. Beautiful, but dulls tools fast and chips out as soon as your plane is other than razor sharp. I love the medullary lines and longevity. Probably my favourite
