I bought two Contigo West Loops and a Zojirushi SM-YAE48RA. My wife annexed one of the Contigos and a friend got the other. This left me with the Zojirushi.
Which one is best?
Let’s take a look…
The two contestants share the crown in this category.
To drink from the Zojirushi, you press a button on the side of the lid set. This flips open the lid, giving you access to a large spout.
To drink from the Contigo, you press a button at the back of the mug. This opens the drinking valve from which you sip.
If you don’t flip the lid back all the way when you open the Zojirushi, the lid cover gasket touches your forehead when you take a sip.
The Contigo’s lack of a lid is another bonus, since it’s one less part that can break off.
The Contigo West Loop takes the usage round.
Before you clean the Zojirushi, you have to remove the lid cover gasket and the stopper gasket from the lid set, both of which are made from silicon.
Removing the gaskets while your fingers are wet is a difficult task. I gave up trying after a while.
Before you clean the Contigo, you remove the lid from the main body, press the ‘PUSH TO CLEAN’ button and clean it.
Both mugs require the use of a small brush.
The main bodies of both mugs clean in the same way.
The Contigo West Loop takes the cleaning round.
I made AeroPress coffee to test in both mugs.
Both times, the coffee had a temperature of 66 degrees Celsius (150.8 degrees Fahrenheit) when I poured it into the mugs.
The coffee in the Zojirushi dropped to a temperature of 34 degrees Celsius (93.2 degrees Fahrenheit) after five hours.
The coffee in the Contigo West Loop dropped to a temperature of 30 degrees Celsius (86 degrees Fahrenheit) after five hours.
The Zojirushi SM-YAE48RA takes the heat retention round.The difference in heat retention between the Zojirushi SM-YAE48RA and Contigo AUTOSEAL West Loop over a five hour period.

The West Loop is easier to clean. You don’t have to remove parts from the West Loop to clean it. The Zojirushi’s lid set contains two silicon parts you need to remove every time you clean it.
The West Loop is easier to use. You push a button, put your lips to the lid and drink. With the Zojirushi, you push a button which flips open a lid.
It was a tough call. Both mugs are top quality.
But there is a winner.
