As others have said, running on the water hold up, is a huge risk, any production trapped between water zones will be inadvertently shut off as you see only half the picture.
Water shut off nowadays can be so much more sophisticated and effective then simply setting a plug and dumping cement across the zone.
Id always recommend running both the water and gas hold up tools so you get the whole picture of what's happening and where the water is coming from vs gas. That data should then be used to drive your water shut off strategy. In many cases using this data and then using a hydroscopic diversion chemical gives you the water shut off you clearly need, whilst maximizing production and you won get the data to make an effective decision from just running a water hold up tool and dumping a plug and cement where X marks the spot on the log.
