Ueshiba's goal was to create an art that practitioners could use to defend themselves while also protecting their attacker from injury.
Wrestling is far superior for that, especially since Akido uses so much joint manipulation, which does cause great injury.
If I remember correctly, Aikido originally specialized in defending against an armed opponent. In that context, it actually makes more sense. Many of the routines are laughable when tried against another unarmed opponent, but start to make more sense if you imagine the opponent with a sword.
I think that's why you were dissatisfied with Aikido as a martial art
You are correct, but it goes a bit further. I don't think Akido can be considered a form of self defense, or a martial art.
It is like Tai chi, it may have grown from a martial art, but it no longer is one.
All of the 'techniques' are routines. Routines do not work in real combat.
In many cases I would wager that an untrained opponent would be better off in a fight because anyone trying Akido is going to open themselves up in easily exploited ways, while having a false confidence.
Nobody trained in Akido has ever won a sanctioned mma bout. Ever.
Every recording of unsanctioned fights or sparing between Akido and 'others' ends with Akido-guy getting destroyed.
As an art? Sure. Sport? Sure. Exercise, athleticism etc. Sure.
Combat? No way, you'll get hurt.
The guy I knew had been training for many years, and was quite good. He believed that in a real fight he would dominate any untrained opponent.
Eventually I broke it to him that his art was not combat. He didn't believe me until I took him out back and told him to come at me full force.
I had to throw him to the ground a few times before he would actually try his best. But it didn't matter, his decade of training, and larger stronger build were not enough to challenge my 6 months of Kung-fu and 1 year of wrestling.
If he had been untrained, he may have been able to beat me due to his size and strength advantage. But I wrecked him because he kept trying routines that I would interrupt on him.
I think this is partially the different philosophies of the different martial arts Japan has spawned, and how many are more than just fighting, but also incorporate a philosophy into their systems.
I've been skimming, so I can't say for sure (at work, or else it would get a full read), but I believe this all begins with Aiki-Jujutsu, which has roots back 900 years, but became popular in the 20th century.

So aikido evolved from this style. This style is likely more what you would look for in a true martial art, as I expect (I don't know) that it's "harder" and less "dancey"[sic] than aikido. So why is aikido so different? Well, it makes more sense when you break the word "aikido" down.
In this case, meaning more of a philosophical or spiritual path.
On the other hand, "Jitsu", as in Brazilian Jiu-Jitsu...
So you can see clear differences in the philosophy behind the styles if you understand the etymology of the Japanese names. Most westerners don't, so it just goes over our heads.
So learning how to fight isn't the only element of this particular martial art - it's also a personal philosophy and religious beliefs as well. And this shows in the way the style acts and operates, as it's actually incredibly difficult to reliably defend yourself from a peer or near-peer attacker without harming them.
It may well be that this guy you were with has a mentor (trainer, instructor, whatever), who is teaching him a style that is less on the martial art and more on the philosophy, even he doesn't outright say it (or fully understand it himself; lots of half-learned "teachers" out there, too).
You can see this same difference in philosophy in the difference between judo and jiujitsu.
"Moral pedagogy". Bringing non martial-arts elements into it.
There's a bit there, but I wanted to be thorough. I think that's why you were dissatisfied with Aikido as a martial art - it has these other elements in there that "dilute the water", so to speak. One of the more focused styles (since there are many), or someone who trains in Aiki-Jiu-Jitsu in particular, might be more to the speed of a "true" martial art.
