Confused on where to get life insurance from

I read some negative things about using policy genius. And I had tried a company called SBLI but I felt like I was rushed through and wasn’t happy with the person I got. My husband and I are in our late 30’s and got a quote for 30 years and $300,000 I was quoted I think $35 and he was $42 per month. Ideally we should be getting a $500,000 policy not $300,000 but it seemed cheaper and would at least pay off our mortgage.

I am very lost on how to locate a reputable company. Also my husband goes to appointments for different things and had an issue that ended up being nothing on a CT scan and unexplained and went away on its own, but I’m not sure if he’d be denied over something unexplained. He also has the option to go to other specialists for it but he’s not having the problem anymore and doesn’t want to pursue anything. I’m not sure if anyone can help me based on these vague details! I just don’t know where to begin. I also only got the one quote from SBLI and I know I should get several, just not sure how to find a reputable company at all. I find this so very overwhelming.
