I run a split slide Glock for practical pistol shooting. In that context it makes sense as it cycles faster, is more gas efficient and suffers less from cool down. When your shooting against the clock this makes a noticeable difference.
The big down sides are it cost more, is more difficult to adjust as you need a screwdriver to break it down to adjust the hop, and all the slide cutaways give Lots of ways for dirt and debris to get into the working parts. While cost is what it is, the other two downsides aren’t a problem when target shooting in nice clean surroundings
When I skirmish I use a short slide WE G19x. It’s still more than snappy enough in the context of skirmishing, doesn’t have the slide cutouts to let dirt in and they are cheeper so I bought 2 for the cost of the split slide so I automatically got a spare mag and if I drop one in the mud I don’t need to try and clean it in the safe zone I just throw it in my bag get the clean one out and clean it when I get home (this massively extends the life of your pistol, as cycling a pistol full of grit kills them pretty fast). Also the shorter slide means weapon transitions are faster (provided you practice) if you ever need it.
