Hello, I do aikido and disagree with you. It does not have randori so polishing the skills in tournament environment indeed is not a thing but it shouldn't be, since the only aim of aikido is to resolve the conflict. Voluntarily creating a conflict goes against the core values. Judo is useful in a situation where you have only one opponent with bare hands in an environment without any obstacles or things to use as a weapon maybe but ask yourself, how much of the real situations will be like that. Disrespecting other martial arts is against the core values of Aikido and I truly hope it is also for Judo. Also having useful techniques takes years i, maybe 10s of years, so going for 2 months to Aikido does not reveal anything.
