Short answer: the Willen II for cleaner sound, the Soundcore Select 4 Go for price. The Willen II is more balanced than the first Willen with no sharp treble, but its bass is not that deep and its midrange can sound congested at volume. The Select 4 Go is quite inexpensive for what you get, yet it does not get very loud before quality drops and shows some sibilance on snare and stick transients.
Buy the Marshall Willen II when sound quality outweighs the price for you, and the Soundcore Select 4 Go when the price outweighs sound quality instead.
