MIP displays are always going to be better in bright circumstances than AMOLED.
The brighter the environment the easier it is to see up until the point it is so bright you get reflections. You will want the backlight off in daylight for MIPS displays - the backlight only helps when its dark.
Have you tried a Wahoo? They use transflective screens and are a lot better in bright sunlight.
Update: I ended up getting the Venu 3s. I love everything about the watch, except that the cycling VO2 max feature seems to only sporadically work.
After much back and forth with Garmin support, the support folks finally told me “this functionality of vo2 max may be possible to be seen but is not fully supported to this venu 3s device. Under a perfect scenario it may display but shouldn’t be mainly used for that value.” (Support only admitted this after they tried to convince me that the rides I’d sent them didn’t meet the requirements to trigger a new cycling VO2 max and it took me specifically identifying two sections of one ride that independently should triggered a new VO2 max estimate according to the manual for them to send me the response above.) I’m not sure now whether I’ll swap the watch or keep it. Very frustrating.
Yeah the Venue isn’t my cycling computer, it was strictly a Whoop replacement that had some fitness applications.
1040/840 are what I use for rides.
I’ve got an Elemnt Bolt that I primarily use for rides. I need to decide how much I care about the VO2 max estimates – I really like everything else about the watch and don’t need a lot of the additional features that come with the Fenix and Epix.
I love my Epix 2, but I would absolutely not buy it just for the VO2 Max estimates. In fact, if they went away, I wouldn’t even notice.
