Med Device vs. Construction Supply Sales

I've been doing D2D solar sales for the past 2 years and looking to swap industries. The two that seem most appealing would be Med Device (long term getting into Capital Equipment) or some type of Construction Supply Sales (either materials or equipment on the commercial side of things). Both seem like great industries that aren't going anywhere with high growth potential.

I have Bachelor's degree and connections in both industries plus I'm a well performing closer in solar so I'm not worried about getting my foot in the door.

I'm curious about people's experiences in either industry, what's the growth potential in both, quality of life once you're a few years in, and income potential of top earners?
