I can’t really help you on picking a pair. I haven’t heard any you are looking at.
If I had to decide between the Samsons and M-Audios without seeing, feeling, and hearing them I would have to go with the M-Audios just because they don’t have a picture of a couple dudes playing video games and eating potato chips on their main product page 
.
Maybe someone else will stumble along who has some personal experience with the products you are looking at.
