Me thinks he is asking which is better and for what reasons. Multi point fuel injection (MPI) or good old fashioned carburetor. Both work fine however I would expect that the MPI being computer controlled would do a better job at controlling the fuel air mix. Just my 2 cents.

Fuel injection so much easier to tune . It's hard to find anyone who knows how to do carb work .

ok, I gotcha now. MPI to me means magnetic particle inspection. If you know how to tune a carb yourself, then go carb all the way, but it's a dying thing and so very few people outside the hotrod world can do it properly. Lets face it, a carb is a much simpler (relatively) piece of technology, it's 100% mechanical so there's no issues with electrical or programming.

The fuel injection has it's benefits too, it's more adaptable, and like Rans said, it can calculate the A/F ratio and adjust to get the optimal burn rate.
