It is not necessarily better, since it probably requires you to bend your wrist. So you solve shoulder pain and get wrist pain in exchange. Also, you probably want to tent a keyboard to avoid forearm pronation [1] and then your trackpad hides between the keyboard halves unless you raise it.

(I am not sure there is a good solution outside avoiding the mouse by using a mouse layer or something like Shortcat on the Mac.)

I'm sure it's not for everyone, but I solved this in a unique way. I have a steeply tented split keyboard, and a trackpad on its own angled mount. The trackpad sits just past the number row on my right keyboard half.
