I like most of the ghost protein powders that don't have bits in them (some have cookie bits; I can't handle the texture, but they're probably better blended with ice and not just shaken in a shaker bottle). The cinnabon one is dead-on, and really good with a bit of coldbrew instead of just plain water
Most of the proteins by Optimum Nutrition are decent to good.
There are some clear whey proteins now that have fruity or lemonade flavors. One tastes like a melted bomb pop (popsicle). I like those in summer.
These taste almost exactly like bubble tea (but don't come with boba; add your own IIFYM):

To make most powders more manageable, blend them with ice and fruit for smoothies. Things that were unpalatable plain are easier to get down when cold and somewhat disguised.
