What is the best karma or rep point system out there now for 3.7.2 ?
 

I tried k bank but it had to many features. What are most people using on 3.7.2 ?

I'm not sure what you mean. Reputation is built into vBulletin.

vbexperience

use VBPLAZA NOTE: it is not for free!

If your talking about a point system, I recommend vBCredits. It's stable and supported.

If you mean a point system, vB Credits is truly amazing for this, and has lots of useful features (credits can be given or posted for example, like rep or karma). It will also integrate into many products, and a shop system which is in development.

i think vbplaza is better " i use it :p" the problem is that it cost 50$, but hey! good things cost good money ;)

vB Credits has far more features and likely better add ons though.

Vbcredits is a great points system

Vbplaza .. err not so much
I use both
