It will suffice from a security standpoint if you know how to maintain it, secure it, and not lose it. 

I think most people discount just how unprepared and "tech security illiterate" the average person is. Yet many have decent amounts of money and want to get into #Bitcoin. In this case the "simple" solution is highly likely to result in disaster.

Example, someone I've been talking to who  have been buying bitcoin just lost his phone twice in 2 months, got tricked into buying rallycoin by coinbase jsut before they delisted it so he can't get rid of it, and now thinks he sent bitcoin to his green wallet but it never showed up (i still ahve to investigate this one).

The guy wants to put his savings into bitcoin but his life is pretty crazy and I honesly don't feel safe telling him to do this unless I can make him a setup that's easy to understand and recover from WHEN those things happen. I think the best option is to distribute among many devices. 

 Exposing your entire UTXO set to a KYC third party is a bigger risk IMO and there is no guarantee they won’t “lose” they key or get hacked and can’t retrieve it 
If they want to save in bitcoin, learn proper OpSec, it is not hard. They just have to put in the time 
And never advise someone to put their entire stack on one type or model of HWW. 
Distribute the risk with different companies

Yes an I don't know anyone besides myself that cares. They can't be bothered because things mostly work okay.
