Some of my observations about the plan mentioned by you -
1- Kotak Life e-term offers flexibility to Step-up and Step-down (increase or decrease of sum insured) your insurance cover in future (no need to buy new insurance policy).
2- Kotak e- term and LIC Amulya Jeevan - you can pay premium monthly/quarterly/half yearly/yearly mode in others only yearly mode. But ensure that you select annual premium payment option instead of monthly/quarterly/half yearly payment, it will save your premium outgo.
3- ICICI Prudential Life Insurance iProtect also provides you option to buy ‘Accidental Death Benefit’ Rider on payment of additional premium. This accidental cover - only cover, death due to accident. So better in addition to this go for general insurance PA cover from other companies like IFFCO-TOKIO, ICICI Lombard, HDFC Ergo, New India, National etc., which will also cover you for Permanent and Temporary disability benefits.

Kotak Life e-term and ICICI Prudential Life Insurance iProtect – both are new policies and so it’s not possible to judge their claim ratio in such a short span. LIC is there for long so we have full statistics available.

Always disclose correct income, health issues and other insurance policy related details in the proposal form.
