Is cumming handsfree while bottoming as good as a regular orgasm?

I'm specifically talking about when you actually ejaculate without any stimulation of your dick.

I've heard some people say it's less intense, some say more intense. I know some people like it because it feels more submissive but what about the actual sensation.

I have been trying a dildo on myself for a year or so and it's generally enjoyable. If I get into a rhythm I can have what I think are dry orgasms (although it's more like a prolonged overwhelming good feeling and not a peak and come down like a regular orgasm).

And then sometimes I get into a rhythm where I feel like I'm gonna pee/a burning sensation at the end of my dick. If I let go then I end up peeing. Or I'm just at that sensation for ever and I never cum or get over the hump. It feels good but I'm just wondering if it's significantly better to actually ejaculate from this. I think I'm close bc thick precum or maybe actual cum does drip out but not very much.

Anyways I'm just curious about what it actually feels like. I've noticed that if I cum using my hand while having the dildo in my ass it kind of "mutes" my orgasm if that makes sense. It feels great up until I cum and then it's like nothing even though cum comes out. I hope a handsfree ejaculation doesn't feel like that, it's pretty underwhelming.
