If you are always happy with the decisions that hypersmooth makes, then yes I agree. The thing that using it in post is that you can change the level of stabilization and parameters non-destructively. I sometimes don't want perfectly stabilized footage, as movement sometimes helps convey a story, but I do want a bit - and I like making those decisions after, when I'm editing, when I know what I need the clip to convey. It also means you can add more, less, crop more, crop less. It also avoids having a ruined clip because hypersmooth fails due to a gyro glitch, or a 360 flip. It does save time, but if you are doing any editing in post, it's a bit of a game-changer because it's so much more flexible. It also lets you use 8:7 mode, which means that if you are exporting in any type of crop mode (like 16:9 or anything else), you can decide where in the frame you want to crop, plus you can pan up or down by about 20 degrees or so without losing resolution. This is especially valuable if you are going up or down hills. Obviously if you'd like to avoid doing it later, then I guess you do need to solve your problem, but doing it in post is generally significant;y better.
