I think you'd be a fine home for a gsd,,good set up
I like both males and females for different reasons..I have to say tho, if I were to have ONE dog, I have loved my doofy, velcro males, easy trainers, biddable.
I love my female (she is my 2nd one, I've always had males), are alot of fun, more serious, I think they mature faster, mine have been more 'guardy' of me than my males .. kinda hard to explain as all dogs are different.
My males were all very mushy, touchy feely dogs, while my females are/were affectionate, there 'hugginess' was kinda on their terms..
Both genders, well lets just say I haven't been in a bathroom alone for many years, very devoted, loyal, ALOOF, (I like an aloof dog! one who is into their owner and the heck with the rest of the world)...always checking in, if your out on a hike, ..
again, hard to explain just what mine have been like..
