Remove vBSEO and 301 redirect old url's to mod_rewrite URL of vBulletin 4?

[Majora]

Hello,
should I remove vBSEO from my forum? I want to remove vBSEO and redirect the url's to the vBulletin 4 mod_rewrite URL's.
Are there any case studies about removing vBSEO and move to vBulletin 4 url's with 301 redirect?

Are the vBSEO functions outdated and a risk for search engine ranking?

Fore me, there is no alternative to vBulletin. vBulletin is easy to use and to configurate. There are a lot of plugins for it.
I hate the design of XenForo and other forums software. I think I will stay on vBulletin for sure.
vBulletin has the functions I need.

Some peoble said, the vBSEO functions are outdated and very risky with SEO.

I removed vBSEO and 301 redirect to vBulletin mod_rewrite URL's on one of my big board forums and i can't believe how megafast my forum is.
Should I remove vBSEO on all of my forums?

Best regards
