I will answer the question in simple terms.
Acceleration: CVT Does not have a gears and are usually single speed, so if you want to abruptly accelerate the CVT will not be as efficient as a manual transmission, the most common problem of CVT is the rubber-band effect where you push the accelerator and after a pause and acceleration increases suddenly. Ergo, a CVT will not outrun a manual transmission at all. Manual is by far a better option.
Fuel Economy: In the hands of 90% of the public the CVT will generally be more efficient than the manual transmission , this is the reason we are seeing a lot of CVTs now a days, they offer better gas mileage and hassle free driving with the disadvantage in acceleration and performance which is just about the normal requirements of a daily commuter. Now in the hands of a seasoned manual driver, he can extract as much or even more gas mileage than the CVT but its generally not worth the effort.
Maintenance: Obviously the manual will be the best , fewer parts fewer wear and tear and fewer maintenance. Plus any wear on a manual gearbox will cost very less when compared to repairs on a CVT.
CVT only provides really two things: Good Economy and the joy of a automatic transmission in bumper to bumper traffic, so if the purpose of the car is strictly going to be commute in the city then the CVT is the better option but in every other aspect the manual is the best also the manual gearbox weighs a little bit less reducing the overall weight of the car.
Note: IF most of your driving is going to be on the express way/highway then save yourself some money and get a manual because in the express way manual can give equal or even better gas mileage and you wont have to worry about constantly shifting.
Also, A CVT variant of the car will also cost more upfront.
