I'm not looking for the best out of these I'm just looking for the most fun champs out of these 6 champs. I was looking for a champ that you can play with and not get bored with quickly or not at all. And these ones seemed the coolest out of the bunch I've seen and played with.
Rikotsu1 votesVarus (mainly if you like his Q/Sniping playstyle) > Lucian > Zed > Thresh > Zac > Khazix
That's my personal preference in terms of how I enjoy them. ^_^ I'd recommend trying them out though before you buy any! :D

DocSmoothJew1 votesThresh and Varus to me don't have a very high learning curve whereas Lucian and Zac take a bit more to get at least decent with and finally Kha and Zed are the toughest to get a good grip on but seem to be very rewarding. That said, I don't think Zed is all he's cracked up to be (albeit I'm still trying to up my proficiency with him). But objectively he feels like he blasts one person out of a teamfight then has to hang around the fringe and mop up. I find that (again, objectively) Kha can be far more effective in teamfights.
Mind you I think both are not your best pick in teamfight lineups compared to ganky lineups but Kha feels like he'll bring more to the table with a more reliable slow and better escapeS (capital 's' on purpose).
In terms of fun I think it depends what you like.
Oh and rengar is a option to I forgot to put him in their
