Anyone uses Snort for OT/IoT/ICS monitoring? If yes, how is your expereince? any tips?

Hi, im wondering if if someone has used snort as an IDS specifically for OT envoirnments. Ive seen there are OT related rules in snort (600 in total if im not wrong) for different OT/ICS protocols like modbus and IEC 104, but ive also heard someone say that Snort isn't recomended for OT envoirnments. Im taking it with a pinch of salt because said person is also affiliated with a company that sells its own OT monitoring solutions …
