The 4448 is a higher quality diode than the 4148, it has a lower reverse leakage current, and a marginally lower forward volt drop.

The 1N4448 can handle around 500mA compared to only 200mA for the 1N4148
The forward voltage under load is prety well the same at 1 Volt max.
I would use the 1N4007 they can handle 1Amp and are a bit more forgiving,and drop 0.7 Volt at load
