Either breed while your in school will be a handful. We had a border collie growing up and I've been around Shepherds all my life. Both shed a fair amount. I will say I think the border collie is a little easier.
I'm not trying to discourage you but maybe you should wait until your out of school. You could have either dog for upwards of 15 years. That is a lot of responsibility with your studies, job, relationships, etc. I'm not saying it can't be done. I did it but it wasn't perfect nor easy.
A GSD pup is a handful for sure. Both breeds are extremely intelligent and take a lot of care. Both breeds are wonderful and will make great companions. Both breeds need a job to do. Neither will like being alone or ignored for long periods.
This will be a tough road, just make sure your up for the challenge. You can't go wrong with either breed but I'm partial to GSDs.
