Some selection of Thomas buses - Help!

[kapa]

Hi guys!
I'm so new on school buses and buses general I don't even know where do begin.

(I did read some old posts, OK!)

Anyway, I got a place with few Thomas buses, but before I go and check them out, which one of them I should put my most attention to?

I read in this forum about Mercedes buses having mixed opinions, some say they are not good and some say they are fine.
I'm so confused with names and companies.
They have Freighliner logo? And then some people call them International and then you see a Mercedes badge on its nose? And they are all Thomas...?
So what am I dealing here?

Would those buses be worth to check out?

Any info is so appreciated and grateful!!

Thanks in advance!
