I would have to go with the ring as long as it comes with a battery or maybe infinite power, kinda like the web shooters being infinite. The gem would be cool but apart from the whole servant of Cyttorak thing, what happens if like Cain you get stuck in cement. The symbiote would definately take over or possibly leave you halfway through a web swing. But unless the symbiote is Venom or an offspring of Venom then your screwed cause the original symbiotes used hosts up. No for me its gotta be the ring. Though if the Batmobile was on the list I would go with that. It might not really give you any powers, have you getting chased by cops constantly and being a huge gas guzzler. But damn is it cool.

will this be the actual symbiote? Will i get the abilities with none of the negatives? If so, I'll take the symbiote 'cause I can blend into normal society and be a beast in pretty much any professional sport. The ring (and everything else) is awesome but you can use them to your benefit IRL w/o becoming a terrorist/super villain.
Iron Man's armour for me. To have a suit like the movie ones wrap around you like a second skin would be brilliant and little bit scary too!
But saying that to be able to fly, shoot repulsers out of my hands and chest, have nifty little weapons and tank-busting missiles would be extremely fun. I realise most of the other things are more powerful than the suit but I'm not greedy.
I'll also take the suitcase suit as well, for when I'm out and about!.
