Are Injections really better?

My doctor is willing to prescribe injections and they are covered by insurance. When I ask about them, doc says ‘why? what makes you want injections’ and I say ‘well I’ve heard they’re better’ and he says ‘he doesn’t believe theres a difference that he knows of but he’d be happy to prescribe them’. I say ‘no no it’s fine’. so is there evidence? what’s the difference?

Thanks!

Edit: wow everyone thank you so much good ask the replies!! Lots to think about. One thing that seems weird to me: my doc has me taking two pikas in the morning and that’s it. Not multiple times a day.

I do want to try injections I think.
