lionel,
Neither one is 'better'
It all depends on what you would prefer, what purpose you are going to use it for - as rifle choices are highly personal.
For me, I prefer the TX200, others the HW77.
Out of the box, they shoot very similarly, handle similarly, cock similarly etc.
Handle & shoot some examples yourself, and see which you like.
Have fun & a good weekend
Best regards
Russ
