Quick Verdict
For me, the Stanley Quencher ProTour is the better Quencher.
The two tested bottles are both 30 oz, cost about the same, weigh almost the same, fit cup holders, and use the same general Quencher body concept. The real difference is the lid.
The H2.0 FlowState lid gives you more drinking positions and supports hot drinks in our tested configuration, but it is not leakproof.
The ProTour Flip Straw Lid is leakproof, partially protects the mouthpiece, is more comfortable to drink from, and cleaned a little faster in our test.
If I am buying a handled tumbler because I want to carry it around rather than leave it permanently upright on a desk, leakproofness matters more to me than the extra FlowState position.

Bottle Details
This is as close to a controlled product comparison as we get
Both WBA-tested configurations hold 30 oz.
Both cost around $40 in our current data. Their heights are nearly identical. Their empty weights differ by less than one ounce.
Stanley currently offers both Quencher families in multiple sizes. The H2.0 family includes sizes such as 14, 20, 30, and 40 oz. ProTour currently spans 14, 20, 30, 40, and 64 oz.
The body concept is similar enough that the lid is the main reason to choose one line over the other.
ProTour is leakproof. H2.0 is not.
This is the deciding difference for me.
The ProTour passed our leakproofness test. The H2.0 did not.
Both work one-handed. Both had Mostly Secure accidental-opening resistance. Both were Medium to open and Difficult with wet hands.
But the ProTour scored Comfortable for drinking comfort, while the H2.0 scored Medium.
The ProTour mouthpiece is also partially protected when closed. The H2.0 drinking surface remains exposed in the tested configuration.
The H2.0 FlowState lid does give you more drinking modes: straw, sip opening, and open-mouth access. ProTour gives straw and open-mouth access.
I understand why someone would prefer the FlowState flexibility. I just value being able to seal the tumbler more.
H2.0 is slightly better thermally
Both started our 24-hour cold test at 1°C (33.8°F).
The H2.0 finished at 12.4°C (54.3°F).
ProTour finished at 13°C (55.4°F).
That gives H2.0 a small 0.6°C (1.1°F) advantage.
The bigger versatility difference is heat. Our tested H2.0 configuration supports hot drinks and finished the 12-hour hot test at 55.1°C (131.2°F).
The ProTour Flip Straw configuration is cold-drink only.
So if hot drinks are part of your routine, the H2.0 immediately becomes more useful.
ProTour is a little faster to clean
ProTour took 3 minutes 25 seconds in our full cleaning test.
H2.0 took 3 minutes 50 seconds.
That makes ProTour 25 seconds faster.
Both bodies are easy to reach with a sponge. Both lids have multiple pieces and neither is a minimalist cleaning experience.
The difference is not huge, but it is another small daily-use advantage for ProTour.
Portability is almost a tie
The H2.0 30 oz weighs 19.16 oz.
The ProTour 30 oz weighs 19.75 oz.
H2.0 is only 0.59 oz lighter.
Both have a high chance of fitting standard cup holders. Both handles fit four fingers and both scored Medium for carrying comfort.
Their heights are also almost identical.
In practical terms, I treat portability as a tie until I think about leaks. Once I do that, ProTour becomes the more genuinely portable tumbler because I can seal it.
Durability is also a tie
Both lid mechanisms showed no noticeable change after 500 cycles.
Both exteriors showed cosmetic wear while remaining fully functional.
The current durability category scores are the same.
That makes sense: these are closely related products built around the same general Stanley Quencher platform.
Which one should you buy?
Choose Stanley Quencher ProTour if…
I would choose ProTour if you want a Quencher you can actually seal.
It is leakproof in our testing, comfortable to drink from, one-hand friendly, cup-holder compatible, and slightly faster to clean than the H2.0.
The main compromise is that the tested Flip Straw configuration is cold-drink only and does not give you the same multi-position FlowState lid.
Choose Stanley Quencher H2.0 if…
I would choose H2.0 if the tumbler will stay upright and you value multiple drinking modes or hot-drink compatibility more than leakproofness.
It kept water slightly colder in our test, is fractionally lighter, and the FlowState lid gives you straw, sip, and open-mouth drinking.
But for my normal use, the lack of leakproofness is the bigger compromise.
If the prices are the same, I would buy ProTour. It fixes the single Stanley Quencher weakness that bothers me most without changing the basic Quencher experience.
How we test products
Every product we review is tested using the same structured process, with dozens of measurements and checks covering areas such as thermal performance, lid usability, cleaning, durability, portability, and everyday use. Those results feed into the WBA Score, which helps us compare bottles using consistent criteria instead of relying only on manufacturer claims.
