Upgrade to 3.5 first?

I plan on upgrading my forums to 3.5. On my existing forums, I use hacks that will probably be replaced by vBSEO (which from what I understand is ok). Should I upgrade my forums to 3.5 and then install vBSEO? OR should I install vBSEO, then upgrade to 3.5?

Is there any difference? Any recommendations?

@cmeinck:

The installation process for vBSEO is very simple (under 5 minutes) for either 3.0.x or 3.5. So you can install vBSEO now on 3.0.x to take advantage of its SEO if you would prefer to schedule your vB 3.5 upgrade for a later date.

In general 3.5 is better & you will be able to take advantage of vBSEO's compliance with vB 3.5 automated emails.
