The KeepCup Helix Thermals, the steel ones with the twist on lid, have an anti spill platform underneath the drinking hole and seem pretty good unless you truly upend the cup. Downside is they’re a bit more fiddly to clean, the drinking hole cover is significantly stiffer, and I’m told by the frothy coffee people at work that they’re a lid off job for a cappuccino not to end up all wrong texture wise when drinking it.
