I like the buckets. Here's why:
1. Light weight.
2. Opaque (no chance of light damage)
3. Easy to clean
4. No blow-off.
I know that glassies will claim that there's are easier to clean, but here's my method:
Hose out the bucket to get crud or dust out.
Fill bucket to the tip-top.
Add 4 tbsp household bleach
Stir with racking cane.
Throw all your tools in there. (can't do that with a glass carb)
Let it all sit while you boil. Use your bottle brush to get anything stuck-on off.
Dump, fill again with water and no-rinse sanitizer right around the time you add your finishing hops, then dump again.
The bleach kills any odors and nasties. You end up with a complete set of sanitized equipment.
Likewise, I'm considering using my bottling bucket as a secondary while my Kolsch occupies my true secondary.
