Yes, there will be no set rule. You would need to try both inverting and
not inverting for each op amp.

For the OPA653 the noninverting configuration has lower distortion at
least for 2V pp outputs.

Just a FYI, some op amps have lower distortion in inverting mode than
as a follower. This is not intuitively obvious since a follow has
maximum feedback, which would imply the best linearity. However the
distortion as a follower is due to the common mode rejection of the op
amp. That is the inverter has the front end differential pair at a
virtual ground while the follower moves the differential pair with the
signal.
