I had one for 10 months. So from when Obamacare was passed till 2019, my employer's insurance got drastically more expensive and worse coverage with both the employer and insurer blaming the rate increases and worsening coverage on the ACA. For 2019, we had dropped below the magic number of employees to have insurance be mandatory and been presented a 30% rate hike so my employer dropped health insurance and told us how to get on the Marketplace. The cheapest silver plan I could find was $250/m after credit (which was more than I had been paying for a company plan in 2018). My wife was on a similar plan for $100/m after credit. She got a job with the state, and we moved up the wedding so I could be put on her new insurance which is both great coverage and super cheap. My employer brought back insurance for this year, but it's silver-equivalent and so expensive that some of the guys are just getting self+spouse and putting their kids on CHIP.
Oh, and I have a preexisting condition, diagnosed at 12. Actually filled my prescriptions earlier this week, meds would have been $3500 at full retail price for a 3 month supply, but after insurance and discount cards I only paid $65 out of pocket - again, awesome insurance.
Worth pointing out to everyone generally - if you're on any kind of meds, look into whether or not the manufacturer has any kind of copay discount card available - for one of my meds it limits the copay to $25 per month, $50/3 months. For the other it's $5/$15, max $100 discount/month. They are put out by the manufacturer of the drug, and they discount your copay and are fabulous if you are on any drugs that don't have a generic.
