First off, there's a few reasons why Sivir was originally listed as the best Solo Queue AD carry: her spellshield makes her safe, she shoves lanes and towers like no one's business and, most importantly, she can be an initiator in a role that doesn't have generally doesn't have that option. Her Ult is as huge a "START KILLING STUFF NOW" signal as an Amumu ult, with the added benefit that you're not burying yourself in the enemy team while yours stands there and watches you get murdered.
Secondly, whenever in doubt, Ezreal is a good pick. He has no bad match ups. He is extremely safe, so that even if your team is filled with morons that can't protect you, you will still get out alive. He does well with most supports.
Any other AD carry is a toss up. Yes, Vayne or Twitch can snowball out of control. But they're risky picks. Yes, Caitlyn can dominate her lane, but is fairly useless past laning phase compared to other ADs. Yes, Tristana is my favourite and I'll pick her into anyone (other than Draven), but she's not a good choice for Solo Queue if you're not sure of your own abilities.
As to Jinx, she is a solid pick, that does well in lane and thrives on chaining objectives. However, she also runs into trouble vs some of the more commons picks. Caitlyn or Sivir give her problems in lane. Vi in the jungle is horrible for a Jinx.
