There are many helpful analyses of the bills available. Here are links to a few:

Keep the pressure on your Senators and Representatives. These bills are disaster. They need to take steps to stabilize the Affordable Care Act. The Democrats are ready to work on it. As Kevin Drum at Mother Jones puts it:
... “Keep Obamacare but fix it” is practically the Democratic rallying cry these days. There’s hardly a Democrat alive who doesn’t loudly and publicly support this position. A couple of months ago all 48 Democratic senators signed a letter promising, “If repeal is abandoned, we stand ready to work with you to help all Americans get the affordable health care they need.” Every liberal rally and march includes people carrying “Don’t repeal it, fix it!” signs. I’ve personally written multiple times about this, most recently two days ago: “Obamacare’s modest problems could be fixed with nothing more than a few minor changes and additional funding of $5-10 billion or so.” Those minor changes include, possibly, a higher mandate penalty and continuing to fund the CSR subsidies. Nothing all that hard.
A detailed report on ways to stabilize the ACA can be found here:

But Trump has said if there's no repeal and replace bill, just let Obamacare "crash and burn". That doesn't sound to me like he's on the side of those who voted him into office.
