I have a Garmin Marq Aviator and I have experienced a lot of crashes, starting from not reading the temperature to issues with the altimeter. I think that the more electronics it has, the more complex it is. But we are in an advanced age and we want fancy things. Never the less, I contacted their support immediately after experiencing these issues and they were first, most importantly, very friendly and second they fixed the issues in no time. I understand that because of the different vendors and people you experience, you will see different characters, but I was happy with these ones. Thanks!
