That one more click is still rogues getting a nerf. While advantage is (too) easy, it is an unneccesary part of the UI with needing extra clicks and actions and it only works on that one clickable attack. Sneak attack should be once a turn on a succesful attack. You should be able to get it on off-hand attacks too, if the first main-hand misses.
And while just a minor thing not relevant right now due to no multiclassing (except maybe for tieflings with the smite ability): you cannot combine it with other attacks like smites or stuff like ensnaring strike. It is minor and kind of a niche situation but, still a result/nerf due to how it is handled in BG3.
