Webb resolution is about 0.1 arc-seconds (wavelength dependent) [1]. Event Horizon Telescope (EHT) resolution is about 25 micro arc-seconds (wavelength dependent) [2]. So roughly speaking, since you cannot really compare the two, since they observe on quite different wavelengths, EHT has ~4000 times better resolution than Webb. Note that we don't speak about sensitivity here. ALMA array of radio telescopes has a collecting area of 7000 m2, while it is just one of many "nodes" of the EHT. Webb total collecting area is about 25 m2. 1. https://www.jwst.nasa.gov/content/about/faqs/faq.html#sharp https://www.jwst.nasa.gov/content/about/faqs/faq.html#sharp 2. https://eventhorizontelescope.org/technology https://eventhorizontelescope.org/technology
