Who to take up to R4?

DarkEternity

Ok so I never actually thought I would make one of these posts after being a ghost on the forums... But I have to ask outside opinions on who to take up to rank 4. By far my favorite champs are Symbiote Supreme and Venom and I like them both equally which makes this hard... I also love Rogue. Symbiote Supreme already does a **** ton for me and a lot of content that seems a bit more difficult is effortless with him (just a change in playstyle) while Venom completely destroys any champ he can bleed or has a class advantage against along with some amazing heal and a very nice nullify on sp1 (don't forget his buff reroll on heavy w/ armor break and under 18% unblockable specials w/ true strike). On the other side Rogue has quite a nice power steal on the l2 that actually can give me a l1 which is incredibly reliable as there will be bonus damage on top of buff steal and life steal. Any help?
