Hello Harshith,
Well, SFTIs are Self financed technical institutes or Private institutes, So, definitely SFTIs are not govt. college, but their academics, infrastructure, etc... are good, but, in terms of placements it is good but not like the Top IITs, NITs, IIITs, GFTIs etc...
If you are getting a seat in IIT, top 25 NITs , top 12 IIITs, or BIT mesra then go for it ... but if not then consider SFTIs through CSAB (you can refer https://engineering.careers360.com/articles/csab-sfti ), or private institutes through direct admission, or on 12th Marks or other admission processes...
Hope This Helps,
Good Luck, and feel free to ask any further query...
