Are Small Finance Banks Worth It for Fixed Deposits?

I have a few lump sum amounts that I want to invest in fixed deposits as an emergency fund. I was searching for banks that offer higher interest rates on fixed deposits.

After visiting multiple websites, including Paisabazaar, I found that among the top 20 banks offering the highest interest rates, 10 are small finance banks. So, I want to know if these small finance banks are worth investing in. I know they are regulated by the RBI and provide DICGC cover up to ₹5 lakhs. However, that's just on paper. Even when everything is insured, if something goes wrong, recovering our precious wealth can be quite a hassle. We don’t have guarantees on when and how we will get our money back.

Additionally, I believe that due to their smaller infrastructures, they probably have weaker security compared to regular banks like HDFC, ICICI, etc.

So, what do you suggest?

1. Splitting my funds into less than ₹5 lakhs and investing each part in different small finance banks.
2. Compromising on the extra interest rates and investing in regular banks that offer slightly higher interest rates, like Bandhan, DCB, RBL, etc.

Again, I want to clarify that it's not the money I'm afraid to lose with small finance banks; rather, it's the possibility of being harassed if any consequences arise.
