MOST IMPORTANT QUESTION = Vbseo OR Dbseo or Custom Vbulletin 4.x or 5.x ??

[SaN-DeeP]

Before proceeding ahead with vbulletin software for future.
I have few important questions.

1. Vbseo developers sucked and QUIT.. heard enuff about this dont want to argue and/or question, can anyone tell me alternatives ?

2. Dbseo came across this software, to manage/handle my stuff.. not sure if its the right choice as far as security and other parameters concerned..
SEO IS DEAD i know that... lets not discuss it here..

3. Can vbulletin 4.x or 5.x handle our default customizations, specially configured for following.
a. Forumdisplay URLs
b. Memberdisplay URLs
c. Showthread Urls
d. Some vague customizations.. (if above handled.. this can be done too)..


We have around 159+ forums (**from a list of more then 400+ **) to be configured.. dont have a hurry though..
Please give proper answer ONLY/.. (will be appreciated if topic goes to point and not argument.. what is or what was better over what).

Sorry for not being active over vb.org for very long time.... occupied MANAGING STUFF.
