I found playing Bass clarinet somewhat easier than playing soprano clarinet. I am not much of a muchness on both of them

but, yes, for a number of reasons I liked the bass more. I am no longer playing bass now.
The embouchure maybe, for some (there are many different embouchures on clarinet and the modern trend is to play in a more relaxed way), closer to saxophone but I would say that baritone sax and bass clarinet have some differences.
Take a look at some videos on embouchure. You will quickly see the differences.
Older bass clarinets have al more horizontal neck and mouthpiece position (which encourages a more saxophonic approach) than modern ones which are definitely pointing upwards to make sure the player has a closer approach to the soprano clarinet.
now take a look at this, different approach.
