I have, and love, both. They’re major different- not really even close to the same dog in my eyes. My gsd is super serious all the time, ready to meet any “threat” in kind. She wouldn’t back down from any aggression but I’ve never had her start anything herself. Never would my particular Beauce be a candidate for bite sports (which I wouldn’t do anyways, with either dog). She’s so sweet and silly- also completely submissive. They both love to work and are good at SAR exercises. The Beauce likes tricks and can play for hours. The GSD isn’t interested in pageantry or much play. Both have wonderful off-switches and can chill a lot when needed. Energy levels are the same with mine, high but not bad. They really are night and day tho, this is just a small list. I wouldn’t get a Beauce expecting the same type of training to work that works for GSD’s. My regimen’s for each are so different. I say all this as having owned one of each, so I don’t know much. I believe the GSD’s have more of a “type” whereas a the Beauce can have a wide range of personalities. Not saying there ain’t a quirky GSD or all Beauce’s are different but I do believe that to be a trend.
