Having rectently acquired a Varia, and using it with a Roam, I think I'd disagree. Perhaps the Varia information looks 'prettier' on the Garmin head units, but the Roam has the considerable advantage of being able to use the side LEDs to display approaching vehicles. The benefit of that is that none of the screen real estate is in any way affected by the Varia information at any time. I started off with the Varia data on the screen, but it's overall a more elegant display mode when using just the LEDs. And, whichever you prefer, you do have the option, unlike the Garmin devices.
Maybe you misunderstood me - that's what i meant ('prettier').
I actually don't mind it on the Wahoo as it functions. I've been using it a few months now and only once has it let me down which was actually yesterday - I knew a car was behind me but it didn't flag it until very very late. Every other time bar none it's worked flawlessly & as someone who isn't the most confident in the world on the bike I would say it's by far and away the best bike 'thing' i've bought, even moreso than the bike computer. Even the time it let me down yesterday, I can't rule out that perhaps it'd jiggled out of position maybe.
But it tells me what it's supposed to tell me, tells me the difference between someone approaching & someone nailing it up behind me. Just doesn't look as 'pretty' as you say.
Though I didn't consider the screen real estate so all in all you're probably right.
Oh, I was just thinking about your use of a GPS watch and wondering about eventually buying one rather than something like a Roam!
I actually bought a second hand Garmin watch recently (735XT) to see if I could make the move to a Garmin watch from a Samsung Galaxy watch (2 totally different beasts I appreciate).
I'd have to look at something packing more features I think if I was to make the shift. I like some things about it but there's things that I don't. It's not the most accurate with reporting how much I've climbed. My times on segments are generally either the same as the Roam or slower, very rarely quicker.
I use the Varia with either a Garmin or a Bolt and certainly the LEDs on the Bolt are easier to see when the display is glared out almost by the sun. The downside with the Bolt is knowing whether a row of red LEDs is approaching traffic or a navigation error.
Ah I forgot to mention - I don't really use the LEDs so I'm missing out there. I really should learn to use them to be honest.
