Should I buy a gen 2? HELP!

Okay so I’ve played SSO for a while, just never bought star coins when I was little or paid for anything. But now I have like 30 horses and they are all gen 3. I’ve never been the biggest fan of gen 2 seeing and I just like the design of gen 3s. But I kinda wanna get a gen 2 just to have one or two. But what two should I get or consider to get?
