to add to what @Austin_Allegro already said: for me personally the reason I switched from the bolt v1 to the edge 530 were the better maps. another advantage in my book are the activity profiles. As many of you I have multiple bikes and like to have different data screens for each activity. IQ Connect Apps are nice too.
I think it depends on how you use a cycling computer. For me the Garmin is still better in many aspects and worth the hassle with Garmins software…
