There are obviously different opinions on this question by different poskim.
People who do shave have whom to rely on.
However, I think it is fair to say the following…
1. It is the “traditional” way (at the least) for Jewish men to have a beard. I
I have heard it said by Rav Amnon Yitzchak that the reason Yemenite Jews call their payos “simanim” is because in Yemen, it being a moslem country, ALL the men have beards, and ALL the men wear a head covering. Soooo, the sign (the siman) that differentiates a Jew from a moslem, is his payos. I would say that in the western (xtian) world, we might, to some degree at least, say this applies to having a beard.
2. Al pi Kabala, “shefa” flows to a person via the beard.
3. “Lift and Cut” type shavers are definitely assur.
