Other Games Which fallout should I get?

So, I watched a lot of videos about fallout and they seem like interesting games. There are 3 of them that are on my list of choice but I kick Fallout 4 out because it was a bad fallout game. I tried it at my friend's and was extremely disappointed...

But anyways, I have two options:

1. Fallout 3
2. Fallout: New Vegas

They're both cool and people for some reason prefer Fallout: NV, but I like them both equally. From what I saw in the walkthroughs, they're both amazing equally. So, which one should I pick?
(Please say why.)

 

I have Fallout 4, and I think it's a pretty good game. What don't you like about it? Also, what are you playing Fallout on? Console or PC?

I would say get Fallout 3 then, seeing as you do not like Fallout 4. In my opinion Fallout: NV is extremely buggy and the story is rubbish whereas Fallout 3 has quite an entertaining and more "moving" story (Boy looks for dad blah blah) and to me NV was basically just a big DLC. Also, Fallout 3's map is waaayy better.

 

I don't like Fallout 4 because the choices don't matter, karma doesn't exist and the quests always boil down to "Kill this guy cause-" but thanks :)

Edit: I play it on PC
