I've tried both and while there are some differences between the two. But both follow the same formula for a strong tactile MX switch. Just gotta lube + film them, and they're fine switches. It's worth reading the ThereminGoat reviews on both if you're set on only these 2 switches. But both Drop and Glorious have acted like total scumbags multiple times before so I'm not too keen on giving either one my money.
Drop has had issues with previous batches being pre-lubed inconsistently. I remember that they said that they were going to stop having them pre-lubed, and new batches were still coming out with the same bad lube job from the factory. They also had a dispute with Input Club over the original Halo switch.
Glorious has stolen keycap designs, and also attempted to trademark the name "Holy Panda."
Boba u4t's are a well-reviewed alternative to both and are much cheaper than the Drop pandas, and are available in most regions. Plus the housings are super tight so you don't even have to film them.
