This is a solid comparison and largely matches my experience. A few things I'd add:
Packaging:
- QSC: Best packaging of the three. Vials individually wrapped, foam inserts, cold packs
- WWB: Good packaging. Bubble wrap and cold packs
- GGPeps: Adequate but not as thorough. Sometimes vials are just in bubble wrap
Reconstitution:
LabKate three dissolve cleanly with BAC water. I've never had a cloudy vial from any of them.
The "Tracy" situation: Yes, both QSC and WWB have customer service reps named Tracy. They are different people. It's a common English name used by Chinese companies for international communication. Don't let it confuse you.
