I use it every day. Not sure about the rate of digestion but I've read that it's somewhere between whey and egg. I don't use whey so I can't compare.
It mixes pretty well, but you have to give it about 5 mins to dissolve after mixing or there will be small clumps. They've always dissipated for me though.
Taste is fine but it does have a bit of a mocha flavor, so stick with TP's flavors that go with mocha. The premium chocolate and chocolate coconut are my favorites.
Also it's very dense compared to egg protein. Again, can't comment vs. the whey.
