Hi Joe--I'm also a Garmin user with an embarrassing amount of Garmin items. 😉 One cool thing about the Vivoactive and other Garmin watches is that most have a custom watch face feature, so you can choose which specific metrics like HR values, target HR zones, etc., you want to see first and often the point scale you want to see them. Garmin does this for their advanced cyclocomputer displays and such, too. The only drawback I find is that the Garmin setups are not always intuitive, so when I upgrade to a new watch (I'm using a Garmin Fenix 6 right now), I usually stick to the default screens until I recognize the features, then play with the metrics displays after I feel like I have stuff figured out and know what I want. In the past I would sometimes set up my Garmin displays based on my previous watch features and overlook cool display options that I initially didn't understand. On YouTube there is a guy named DCRainmaker who puts together comprehensive reviews of fitness products. Sometimes Garmin's user resources include links to Ray's videos, website and comparison charts for explanations on benefits, capabilities, and how-tos. He does a great job of breaking technical things down and explaining the advantages or applications for features, which I sometimes require to fully understand components. I tend to check out Ray's content whenever I'm looking at gear upgrades, too. I hope this helps.

I have the PocketRocket and didn't really consider JetBoil systems until we backpacked with someone who used a JetBoil next to us while we cooked with our PocketRocket. For fun we sourced water from the same MSR camp bladder, so our water and outdoor temperature conditions were identical. When we used identical measured volumes and her JetBoil consistently and impressively beat our PocketRocket in boil times. At breakfast she would be sipping her fresh coffee from her JetBoil while we were still waiting on our PocketRocket to form simmering bubbles at the bottom of our titanium pot. It was clear that the JetBoil saved gas fuel over our PocketRocket, but until this fall I remained leery of JetBoil systems because of their size and weight. Recently JetBoil introduced their compact and lightweight Stash model, which is supposedly '40% lighter' than other JetBoil systems. The advertised system weight (7.1 oz) matches the weight of our PocketRocket Deluxe paired with our similarly-sized titanium pot. I'm waiting on more product reviews, but for extended trips, the JetBoil Stash fuel savings would be a significant consideration for weight reduction.
