PSLV and GSLV are the two rocket launch systems launched by ISRO. PSLV stands for Polar Satellite Launch Vehicle and GSLV stands for Geosynchronous Satellite Launch Vehicle.
Of the two, PSLV is of the former origin. PSLV can launch only over a ton of payload into the orbit while GSLV is more powerful with the capacity to launch around 2.5 tons. GSLV uses cryogenic for its final stage while the PSLV does not use such fuels.
PSLV has six solid booster engines while GSLV works with four liquid engines.
As far as the success rate is concerned, PSLV has proved to be more reliable with only one failure among the total of 18 launches so far. GSLV has been a failure with just one success from a total of 7 launches.

The main difference between the two satellites is the presence of Cryogenic engine. This engine provides more thrust to the vehicle (rocket) for the same amount of fuel.
PSLV used to send satellites to the lower orbits. whereas, GSLV used to send satellites to the higher orbits and also higher loads.
GSLV success rate is very crucial here as it enables us to send more commercial satellites into earths orbit and also can improve communication technologies.
