For me B is really great but way to classic and i think that A actualy look technicaly cutter with his droppy ears. Small change for A could be great because for me he is kinda too perfect He need something to make him look less simple. So for me specie B is better but way too classic and design A look great and have personnality so... If you manage to make a real personnality for design B then i Will probably prefer him but as it stand design A is more original and look as great as B
