It’s really down to what you personally resonate with, in my opinion. The Lesser Banishing Ritual of the Pentagram is considered to be the gold standard of banishing in ceremonial magic and it is very powerful when done well, but there are also many different variations on it that people have created and used successfully.
For example, some people don’t vibe with angels so they swap them with different entities, like demons, which then provides a different flavouring to the basic ritual, such as in the Banishing Rite of the Dark Lord.
I personally enjoy the Lesser Banishing Ritual of the Pentagram, and some of its variations, but I also enjoy Jason Miller’s Hecate Banishing from his book Protection and Reversal Magick. I find it to be quite powerful. I’ve also used Damon Brand’s Circle of Power, which is streamlined but still remarkably good. If I’m in a hurry, I’ll use a banishing incantation to clear my area instead of a full banishing ritual.
The most powerful banishing, though, is the one that speaks to your mind the deepest with its symbolism. The pentagrams, and beings invoked, have to strike a chord with you in order to be effective. Sometimes, the best banishing is simply to bellow in a loud voice “Fuck off, ya assholes!”
