I should note that the two main Zephyr Heights royal guards went instantly to protect the two princesses, and didn’t immediately get their pony butts kicked by the main villain to get to them.

Neither, they are both hopelessly incompetent, underequipped and purely for show.
@Mr.Myoozik
With guards like these, that’s the best option.
@Scope
How about we have several tens of thousands of clones of you and then we’ll get somewhere.

ZH. Maybe less for protection and more that they look fun to mess with. Four legged chickens in fluffy helmets

Canterlot. Zephyr Heights doesn’t look like they know what they’re doing.

ZEPHYR HEIGHTS FOR THE WIN!!!!

Let’s put them up against Ezio first

Both are pretty awful.

@Incursor
After for sure. They couldn’t even fly before.

Before or after magic returned in G5?

If before Canterlot because they’d at least have magic to be useful outside of their incompetence in combat. We haven’t seen how ZH guards fare with magics return to compare.

Zephyr heights seems better organized

I can protect myself, thank you very much

It’s the Imperial Stormtroopers versus Starfleet Security Officers (redshirts) fight all over again.

Well, Zephyr Heights royal guards at least managed to arrest their Queen, so they’re definetely have some nuts

Pegasus guard seems moderately less incompetent.

Neither.

The ones that want to hug me.

Canterlot, any day

The problem here is they are essentially monoracial. The Canterlot guards are all unicorns, and while that suggests an advantage, we have no idea of their magic abilities, which could range from Sweetie Belle to Starlight. The ZHG are all Pegasi, which paired with modern weapons would make them deadly attack helicopters. IF there were any weapons beyond glue guns.
As for ‘service’the ZHG make great waiters. Just keep them away from the decor.
For protection, give me a handheld Flurry Heart and stay out of the way.

I would be doomed either way.

I’m sure they have good days.
You just don’t see it on the show a lot.

canterlot guards looks more impressive i think

Neither.
