Get the clear ones. You can see what is going on inside. If you have smaller diameter than 14 gauge (so higher gauge), you can put more than one wire in each slot; so a 5 slot could hold a qty of 15 (3*5) gauge 22 wires. I have done this inside a mod of an MTH full length vista dome. Also for temporary low voltage setups at work. DO NOT DO THIS FOR HOUSE WIRING.
The bonus of buying Wago over cheap Chinesium is the Wago are UL approved, can use then for your house. I found the UL approval for the three slot clear on this page:
