We have been using an AVMAP Ultra for about a year in our C42. It was simple to install
as replacement for a regular VSI, a little bit of a faff to calibrate but once calibrated it’s been flawless in operation. I bloomin love it. It’s got more capability than the garmin and it’s perfectly readable in bright sunlight. It’s just not quite as “pretty” as the G5 but unless that’s your priority or you’ve got other other Garmin boxes to connect to I can’t see a reason not to opt for it at the price point.
One feature that hasn’t been mentioned here is an emergency capability to navigate using a form of inertial nav ie without any form external reference including a GPS signal. You’re going to be having a bad day if you have to rely on that but it’s there.
