In terms of educational quality, both are fairly similar. However, selecting a university is also influenced by a number of other factors.
If you're thinking about getting an MCA, Symbiosis is a good place to start. The same college's MSc CA programme is well-known, and people who complete their masters get really good jobs. However, if you intend to work immediately after completing your BCA, Christ is a better option because it is located in Bangalore, India's IT capital.
Tuition fees are nearly identical in both colleges. Symbiosis BCA costs INR 1,000,000 in the first instalment, INR 67,500 in the second, and INR 1,52,500 in the third, whereas Christ costs INR 4.07 Lakh.
However, the cost of living in Bangalore is significantly higher than in Pune.
The weather in both cities is drastically different. When it comes to public transportation, Bangalore far outperforms Pune. However, it has its own drawbacks. Bangalore has terrible traffic, whereas Pune is still on the better side.
If you really can't decide between two colleges, consider the distance and duration of travel. It is suggested that you select the one closest to your home town.
There could be numerous other factors. Take your time, choose your college wisely, and develop your own metric of consideration when selecting a college.
