It is really tough to directly comment on any institute best or not or answer which is the best institute in a city or country , especially for domains like web designing, animation and VFX or gaming etc. where many institutes offer many types of courses for different duration for the almost all the same pipeline .
We need to see the content of the course , duration, cost , infra, earlier students outputs and skill developed , in-time course completion record , certification process & delivery of certificate in time etc.
Also Same Brand has different centers and branches and fortunately/unfortunately all does not perform the same . Some centers are doing great some not, in vary place to place centers to centers and also on the local management & team.
So its always good to visit the institute personally, speak to them, see the track record and then decide if its up to the mark as per your requirement.
