What's your goal? There are all types of certificates, some cheap and some expensive. If you're aiming for cheap, companies like Namecheap and GoDaddy sell them for peanuts but they're "cheap" certificates, not with bells and whistles.
All EV certificates provide that feature, not just the ones sold by Verisign. Are you a paid shill of Verisign?
In general, no one should ever do business with Verisign, due to their practice of domain slamming, their Site Finder misfeature, and other shady practices.
"VeriSign was sued in 2002 for their actions in sending ambiguous emails informing people, often incorrectly, that their domain was about to expire and inviting them to click on a link to renew it. Renewing the domain resulted in the registration company being transferred to VeriSign from the previous registrar."
Ok, I didn't know that. What I should investigate is whether the same people that authorized those shady tactics are still in charge there (or whether that culture persists).
Mostly, they are the same. There are some "addons" that are possible with SSL certificats. For example wildcard certificats which are valid on all subdomains, included support, encryption strength, browser support and others.
