I have both(kinda). I have LG at one house, IFB at another). Btw IFB collaborated with Bosch/Siemens in the past so if IFB's good, then chances are Bosch will also be good.
For LG, I also have good experience. It's just that LG has DD attached to the drum, so it has more power which can make the machine vobble. If they can tune the power delivery, it's equally good. Mine is 2021 model, so dunno if they resolved this in later series.
For IFB, given it's belt driven so functions are comparatively less than LG. But you'll need to check with Bosch by visiting the showroom.
At the end, it all boils down to how's their ASS later on, say, 5-20 years down the line. Most work good till 5 years. The ones who stick with you without burning a hole in your wallet should be your deciding factor.
