I'm a solo artist (guitar and harmonica) and find this make of harmonica, while blowing "slightly downward" on a neck mounted support, always block up quickly, where Hohner will continue all night without problems.
OK, hand held, these harmonica's, Lee Oskars, do great, even though they sound thin compared to Hohner's.
I keep rotating round all 4 makes to keep up with any improvements, but they must sound good through my "voice mic" as 2 mic's is awkward and my neck is getting old for too much movement.
