If both are as good … WHY then those anti vax still dun wanna jab.
Because of them, many businesses are suffering, hospital & medical staffs under stress and a bloody burden to society.
Karma will fall on their selfishness

There is always good and bad. 

Maybe not safe enough. 
I concern for those who medically cannot take the jab. 
And I feel vaccines can be make safer and method is likely already available

Nasal vaccines offer an attractive alternative to injectable vaccines in that it may be possible to use a lower dose than for IM/SC injection, the vaccine can be delivered to the appropriate site, namely the NALT, nasal vaccines do not necessarily require to be administered by a health-care person, and it is a better alternative for vaccination ...

lower dose very likely make it more safer

Else nasal spray inhibitor can be offer, it will help reduce the chance of developing into serious conditions
even if they are infected.

We need to improve so must the vaccine as well.
