Cheap LED lights are often over-advertised regarding their wattage, try measuring those 20W ones with a plug-in meter. The strobing depends on how the driver electronics are constructed, there are LED bulbs that has practically zero flicker - far less than incandescents even. If you get a name brand like for example Philips or Ledvance (previously Osram), you're far less likely to encounter these two problems. There are good cheap ones too, but it's hard to know which ones before trying them.
The cheap ones are also often over-driven and doesn't last long and/or lose light output over a relatively short time.
The color rendering is measured in RA or CRI (same thing, different names), and there are LED bulbs with higher numbers. None as high as incandescents - 100 - but 95+ exist. The usual for LED bulbs is just 80. The better ones are slightly less energy efficient, and usually more than slightly more expensive, 1.5 to 3X the price, but since only name brands make them AFAIK, they'll probably last at least 1.5 to 3X the time of the cheap ones too, so it's probably worth it, at least in the kitchen/eating area, over the mirror, etc.
