Both models support RAM speeds of up to 1600. In addition, you will be able to install the same amount of RAM in both models, and most probably 16 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.
In total the Dell OptiPlex 3020 MT has 8 USB ports. The Dell OptiPlex 9020M is inferior in this regard and packs 6 USB ports. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals you will need to look at other models.

This is important as there are M.2 slots which support only the inferior SATA III interface. For comparison, the SATA III interface has max speeds of 6 Gb/s, while the PCIe 3.0 x4 will support speeds up to 32 Gb/s!
Having a Power Supply Unit with high power rating is important if you are going to use components which require extra power. The Dell OptiPlex 9020M comes with a decent 65 Watt PSU, but the Dell OptiPlex 3020 MT has a more powerful one rated at 290 Watts.
