Obama's presidency began during or towards the end of one of the biggest recessions in history. Quite important for context. Not to mention that he too faced massive opposition, especially in the last four years of his presidency, from a Republican Senate and Republican House.
Trump supporters seem to be pretending that all these problems are new, but they are not. The system is, if anything, deliberately designed to stifle the President, on the (not unreasonable) grounds that no one person should have unrestrained power.
It's also important to mention that many of the moves towards greater employment etc, sadly now destroyed by the CoronaVirus, were continuations of trends that had started while Obama was in office. In a sense Trump was only surfing the wave on that score.
A more reasonable measure of Trump's success would be to choose his own standards: there were three signature aims he set out at the start of his presidency, namely tax reform, healthcare reform, and infrastructure reform. The last isn't a controversial issue but for some reason he hasn't even touched it. The second was blocked by his own party; the first he did achieve, although it mainly amounts to a tax cut for the wealthy so whether it's a good thing or not is debatable.
