I've got a 1997 26 Scarab. It has run a best of 81 on GPS. It may not be the fastest but I've been complemeted my quite a few people on how it rides. Some of the boats that it was compared to were up to 4 feet longer. It does not chine walk and is very user friendly. Almost anyone can jump in this boat and run as fast as I do. I've never been in a 24 Baja , but the larger ones that I've been in seemed to chine walk quite a bit past the 75mph mark. Now I wasn't driving so it could have been driver error.
These are my opinions but it seems like everyone forget about these Scarabs. I think for the price you get a lot of boat.
Good luck with your choice.
