For the pennies a day or miniscule chance of hitting a solo block I would go for the NerdQAxe++
Yes if it dies / crashes you stop mining.
The other side is that you are only managing 1 device, not 4. So it's more time and effort and things to go wrong if you have 4 things to deal with.
If they were all throwing off $10 a day it's a different outlook. For that little bit of $ do you want to manage more devices.

yeah my single bitaxe is lucky to run a day in a row.
I still argue point them to viabtc.
about 20 cents a day is 72 usd in a year
set the payout to 0.001 and in 500 days you will get a payout of 0.001 btc.
it is a good dca and hodl method.
set the payout to 0.005 and in 2500 days you have 0.005 btc which could end up being a decent piece of change.
