I don't think anyone is expecting the new LTWOO groupset to be as good as Di2/eTap. However, like most budget alternatives, customers seem to still expect 80-90% performance/quality for only half the price. Time and time again this expectation only leads to buyer's remorse.
It's the very reason I prefer a 2nd-hand Shimano Ultegra/105 mechanical groupset versus the stuff from both LTWOO and Sensah. Small moving pieces and components leave more room for failure than, say, a static Chinese bike frame.
