Yes. Even studies show that they give the same results on testing.

I really think the sublinguals are swallowed in the saliva.
But for those who "believe" they work, those individuals should
do so under the tongue on an empty stomach (just to be sure).

The B12 molecule is huge, and not lipophilic and not likely to
cross the small area under the tongue reliably IMO.

Daily oral use is closest to nature too. We were not evolved to
get mega shots every month. But to eat animal derived foods on a regular basis. The study I have linked to in the B12 thread here even shows that the injections only provide about 150mcg per 1000 shot anyway. One would think more but I guess it is excreted as a huge mega dose quickly. I read once within 72 hours. That is why people show up online with injection roller coaster side effects...up and down, feeling great feeling terrible the next day, etc.
