The most important:
The main difference between cgdi mb and vvdi mb is that, on old Mercedes, cgdi mb is able to OBD program a new key while you have to disassemble EIS to add a new key with vvdi mb tool. That is why you should have a cgdi programmer for mb.
More difference...this is feedback from users!

PCB: VVDI MB wins!
CGDI use cheap parts in their PCB , even poor support
BIG difference between vvdi and CGDI
Original: VVDI MB wins!
VVDI MB is original device of which have made a copy and that is CGDI MB
Vehicle coverage: VVDI MB TOOL wins!
Vvdi mb tool support more vehicles than cgdi mb prog
Old EIS: CGDI MB key programmer wins!
I think, you should buy Vvdi prog too, because the are some eis and ecu's that you cant do with MB Tool independently. For example some w210 eis or Sprinter 906. I have both, MB Tool and prog. If I had to buy some tool again, I would think about Simone Touch, but its more expensive.
But if you have a CGDI MB, you have a chance to program a new key through OBD. All done with a tool. That’s the reason why I bought it.
ESL: VVDI MB wins!
vvdi mb can renew esl, cgdi cannot
Token number: VVDI MB wins!
vvdi mb tool can buy tokens alone, it is more suitable for those customers who need more tokens one day, cgdi mb prog do not offer tokens alone, you can get two tokens for free every day, it is enough for personal usage.
Token cost: CGDI MB wins!
CGDI until 6 months after purchase, you have 10 free by days. After 2 free by days. If you need more, you can buy:
free token for the first half a year, then 70 usd for half a year
You can calculate password with tokens twice a day if you have a cgdi or cg pro.
But you can have four times if you have both cgdi and cg pro. (I’ve sent the serial number http://www.chinacardiags.com/ and they helped make them a combination. Now i have 4 tokens to use every day)So, in the token VVDI is very more expensive
And 380 usd without limitation for a year http://www.chinacardiags.com/wholesale/vvdi-mb-bga-tool-benz-password-calculation-for-one-year-unlimited-token-51132.html
Tech support: VVDI MB wins!
CGDI is poor support and no has yet many functions like VVDI, that is a fact.
But CGDI is young, less than 3 months on market, came from a small company without reputation.....
Also in the fact, token is fore more cheaper, calculate PSW very fast and alway first time from server.
CGDI is 1/3 VVDi price, and VVDI is out from almost more than 2 years. So for me, let it grow up and time will tell if this is good tool or not.
I see Xhorse already give unlimited 1 years token, just the time which cdgi come out.
